NEUROLOGICAL EMERGENCIES
Paraplegia and urinary and fecal incontinence: when the body sends alarm signals . Oncological and neurological causes, investigations, differential diagnosis, treatment and prevention – a complete guide for patients
Are you losing control of your legs? Do you feel like you can no longer control your bladder or bowels? These symptoms, especially when they appear suddenly or progressively in a patient with cancer or spinal cord disease, represent some of the most serious medical emergencies in all of medicine. Every hour counts. This guide explains everything you need to know – in plain language, without confusing jargon.
1. What is paraplegia and why does incontinence occur?
Paraplegia is the loss of muscle strength and sensation in both legs (lower limbs), caused by injury or compression to the spinal cord or nerve roots. When the injury is incomplete, it is called paraparesis (partial weakness, not complete paralysis).
Urinary and fecal incontinence occur when the nerves that control the bladder and bowel (located in the sacral segments of the spinal cord – S2-S4) are compressed or damaged. The functions we consider normal – going to the bathroom when we want, controlling our sphincters – depend on an intact nerve pathway from the brain, through the spinal cord, to the pelvic organs.
When this pathway is interrupted – whether by a tumor, an infection, or a massive herniated disc – control disappears, sometimes suddenly.
🚨 MAXIMUM EMERGENCY sign: The appearance or rapid worsening of weakness in the legs, combined with loss of bladder or bowel control, represents an absolute neurosurgical emergency that requires immediate presentation to the emergency room, regardless of the time of day or night.
2. Anatomy of the problem: the spine, spinal cord and critical junction
To understand why these symptoms occur, we need to know a little anatomy:
- The spine is made up of 33 vertebrae that protect the spinal cord.
- The spinal cord extends from the base of the skull to the level of the L1-L2 vertebra.
- Below L1-L2 there is no longer a spinal cord, but a bundle of nerve roots called the cauda equina – which controls the legs, bladder and bowel.
- The epidural space is the space around the spinal cord, between it and the spinal bones. Tumors, abscesses, or hematomas that grow in this space can compress the spinal cord.
Where does compression occur?
- 70% of cases : thoracic spine (middle back)
- 20% of cases : lumbosacral spine (lower part)
- 10% of cases : cervical spine (neck)
3. ONCOLOGICAL CAUSES – Cancer as the origin of paraplegia
3.1. Malignant spinal epidural compression – the most common oncological neurological emergency
Malignant spinal cord compression affects 3-5% of all cancer patients. It is the second most common neurological complication of cancer, after brain metastases.
How does it occur? Most commonly, cancer cells migrate through the blood and implant themselves in the vertebral body. The tumor grows, destroys the bone, and bone fragments or the tumor itself compress the spinal cord or cauda equina in front (anteriorly).
What types of cancer most commonly cause spinal cord compression?
- Breast cancer – most commonly affects the thoracic spine
- Lung cancer – rapid progression, severe prognosis
- Prostate cancer – often osteosclerotic metastases (denser bones)
- Multiple myeloma – extensively destroys vertebrae
- Lymphoma – sometimes compression without bone destruction
- Kidney, thyroid, colorectal cancer – rarer, but possible
Mechanisms of spinal cord compression in cancer:
| Mechanism | Description |
| Direct extension of vertebral metastasis | Most common; the tumor grows from the vertebral body into the spinal canal |
| Vertebral collapse | Pathological fracture of the vertebra compressed by the tumor |
| Extension through the intervertebral foramina | Paravertebral tumor penetrates directly into the canal |
| Intradural or leptomeningeal disease | Tumor cells on the surface of the marrow or roots |
| Vasogenic edema | Perilesional swelling that enhances compression |
| Anterior spinal artery compression | Spinal cord ischemia due to adjacent tumor |
3.2. Primary tumors of the spinal cord and vertebral canal
Unlike metastases (which come from other organs), primary tumors arise right in the spine or spinal cord.
Anatomical classification:
A. Intramedullary tumors (within the spinal cord):
- Ependymoma – the most common primary intramedullary tumor; grows slowly, is often surgically delimited
- Astrocytoma – infiltrative, more difficult to completely operate on; can be low-grade (slow) or high-grade (aggressive)
- Spinal glioblastoma – very rare, extremely aggressive
B. Extradural tumors (outside the dura, generally in the vertebrae or epidural space):
- Metastases (most common)
- Lymphomatous or leukemic deposits
- Multiple myeloma
C. Intradural-extramedullary tumors (within the dura, but outside the spinal cord):
- Meningioma – benign, more common in women; grows slowly but can severely compress
- Schwannoma / Neurofibroma – on the nerve roots; benign, usually operable
3.3. Leptomeningeal metastases (carcinomatous meningitis)
Tumor cells can spread through the cerebrospinal fluid (CSF) and colonize the surfaces of the spinal cord and nerve roots.
Commonly associated cancers: lymphoma, leukemia, breast cancer, small cell lung cancer, melanoma
Hallmark: the simultaneous presence of symptoms at multiple and non-contiguous levels of the nervous system – for example, weakness in the legs + vision problems + headache, all at the same time.
4. NON-ONCOLOGICAL NEUROLOGICAL CAUSES – Other diseases that cause paraparesis and incontinence
4.1. Cauda Equina Syndrome – ABSOLUTE EMERGENCY
The cauda equina is the bundle of nerve roots that descends through the lumbar canal below L2. Its sudden compression is one of the most serious medical emergencies.
Main causes:
- Massive central lumbar disc herniation (the most common non-oncological cause)
- Traumatic vertebral fracture
- Extradural tumor (oncological or benign)
- Epidural abscess
- Epidural hematoma (in patients on anticoagulants)
Classic symptoms of cauda equina syndrome:
- Severe low back pain radiating to both legs
- Saddle anesthesia (loss of sensation in the perineum, in the area of contact with a horse’s saddle)
- Flabby weakness of the legs
- Urinary incontinence or retention – the most serious sign!
- Fecal incontinence or retention , low anal tone
- Abolished or diminished osteotendinous reflexes
4.2. Severe spinal stenosis
Spinal stenosis is the narrowing of the spinal canal, most commonly due to degenerative changes (arthrosis, hypertrophy of the ligamentum flavum, herniated disc). It can affect the cervical, thoracic, or lumbar spine.
When does it cause paraparesis and incontinence? Severe stenosis, especially cervical or thoracic, can cause myelopathy (damage to the spinal cord) with:
- Unstable, uncertain gait, “as if on soft ground”
- Progressive weakness in the limbs
- Loss of bladder control (urinary urgency, incontinence) – a late, serious sign
- Fecal incontinence – rare, sign of severe compression
4.3. Spinal epidural abscess – infectious emergency
An epidural abscess (collection of pus in the epidural space) can rapidly compress the spinal cord, producing fulminant neurological deficits.
Risk factors:
- Diabetes mellitus
- Intravenous drug use
- Epidural catheter (risk 0.5-3%)
- Spinal procedures (injections, surgeries)
- Immunosuppression
- Remote staphylococcal infection (boil, urinary tract infection)
Classic triad (rarely complete at presentation): localized spinal pain + fever + neurological deficit
Most common causative organism: Staphylococcus aureus (50-90% of cases, including MRSA)
4.4. Other important neurological causes
| Cause | Mechanism | Distinctive element |
| Transverse myelitis | Autoimmune inflammation of the marrow | Sudden deficit, clear sensory level, no compressive lesion on MRI |
| Multiple sclerosis (MS) | Demyelination | Repeated seizures, associated brain lesions on MRI |
| Guillain-Barré | Autoimmune polyradiculoneuritis | Ascending from bottom to top, flaccid paralysis, areflexia |
| Spinal arteriovenous malformation | Vascular fistula | Fluctuating, aggravated by exertion |
| Spinal cord infarction | Anterior spinal artery occlusion | Sudden onset, peak in minutes-hours |
| Epidural hematoma | On anticoagulation or spontaneously | Brutal pain + rapid deficit |
| Infectious spondylodiscitis | Disc + vertebrae infection | Persistent pain, fever, elevated ESR/CRP |
| Osteoporotic vertebral fractures | In osteoporotic, post-traumatic | Acute post-traumatic or minor pain |
5. SYMPTOMS AND CLINICAL SIGNS – What to watch for?
5.1. Typical evolution of malignant spinal cord compression (significant for cancer)
Stage 1 – PAIN (weeks-months before the rest): Back pain is the first and most common symptom in about 90% of patients.
- It is located in the area of the affected vertebrae.
- It can radiate along the nerve path (radicular, belt-shaped for the thoracic)
- IMPORTANT CHARACTERISTIC: pain worsens when supine (lying on your back), maximum in the morning upon waking – unlike mechanical pain that improves at rest!
- Worsens when coughing, sneezing, bending over
Stage 2 – MUSCLE WEAKNESS:
- Occurs weeks or months after the onset of pain
- Progressive, more severe in the lower limbs
- The patient notices that he cannot climb stairs, that he stumbles, that his legs “no longer obey”
Stage 3 – SENSITIVE CHANGES:
- Numbness, tingling
- Sensitive level : the patient can locate exactly where the sensitivity stops – a strong sign of spinal cord compression
Stage 4 – BLADDER AND BOWEL DYSFUNCTION (late but critical):
- Urinary retention (inability to urinate) or incontinence
- Severe constipation or fecal incontinence
- Decreased anal tone on rectal examination
- This is the final stage before complete paralysis – urgent medical intervention is essential!
5.2. Differentiated clinical signs: spinal cord injury vs. cauda equina injury
| Characteristic | Spinal cord compression (above L1) | Cauda equina syndrome (below L1) |
| Muscle weakness | Spastic (increased tone) initially flaccid, then spastic | Flaccid (low tone) |
| Tendon reflexes | Initially low, then vivid/exaggerated | Absent or diminished |
| Babinski sign | Present (thumb rises to stimulation) | Absent |
| Anal tone | It may be normal or increased. | Low or absent |
| Sensitivity | Clear sensory level (dermatomal) | Saddle anesthesia, radicular distribution |
| Pain | Localized, with bilateral radicular component in the belt | Irradiation in both legs, lumbar |
| Expedite | Maxim | Maxim |
6. INVESTIGATIONS – What tests and imaging are needed?
6.1. MRI (Magnetic Resonance Imaging) – the gold standard
MRI of the entire spine with and without gadolinium (contrast substance) is the mandatory and urgent investigation in any suspicion of spinal cord compression.
Why MRI and not CT?
- MRI excellently visualizes the spinal cord, nerve roots, discs, ligaments and soft tumors
- Detects compression and intramedullary changes (edema, ischemia)
- Identify the affected level(s) (compression can be multilevel in cancer!)
- Differentiate tumor from infection, hematoma, herniated disc
- Does not radiate
When is an emergency MRI performed?
- Any suspicion of cauda equina syndrome → EMERGENT MRI
- Suspicion of epidural abscess → EMERGENCY MRI
- Patient with cancer + new neurological deficit → URGENT MRI (in hours)
- Rapidly progressive neurological deficit → EMERGENT MRI
6.2. CT (Computed Tomography)
Useful when MRI is contraindicated (pacemaker, metal implants) or as a complementary investigation:
- Excellently visualizes bone structure, fractures, calcifications
- CT myelography (with intrathecal contrast) – alternative to MRI for visualization of compression
6.3. Plain radiographs of the spine
Limited utility, but quickly available:
- Detects vertebral compression fractures, osteolysis, spinal alignment
- Positive in 80% of cases if there is bone destruction
- I DO NOT rule out spinal cord compression if they are normal!
6.4. Laboratory analyses
| Analysis | What does it evaluate? |
| Complete blood count | Anemia, leukocytosis (infection), pancytopenia (bone marrow infiltration) |
| ESR, CRP (CRP) | Markers of inflammation – increased in infection or active cancer |
| Serum calcium | Hypercalcemia – common in bone metastases (breast cancer, myeloma) |
| Tumor markers (PSA, CA-125, CEA, CA 19-9) | Orientation to primary cancer type |
| Blood cultures | Positive in 60% of epidural abscesses – to be collected BEFORE antibiotics |
| Electrolytes, renal function | Basic parameters, important for treatment |
| coagulation | If epidural hematoma is suspected or before biopsy |
6.5. Lumbar puncture and CSF examination
It is done ONLY after excluding by CT/MRI any mass that could herniate at the puncture.
Main indications:
- Suspicion of carcinomatous meningitis (leptomeningeal metastases)
- Suspicion of infection (myelitis, meningitis)
- Evaluation of paraneoplastic syndromes
What is analyzed in CSF:
- Opening pressure (increased in HIC)
- Cytology (tumor cells – positive in 50% at the first puncture, 90% at the 3rd)
- Proteins, glucose, cells
- Cultures (bacteriological, mycological, BK)
- Tumor markers (CEA, β2-microglobulin)
6.6. Other investigations
- Bone scintigraphy / PET-CT – detection of bone extension of cancer
- Chest-abdomen-pelvis CT – assessment of primary cancer extension
- Electromyography (EMG) + nerve conduction velocities – differentiating radiculopathy from peripheral neuropathy
- Biopsy – when the histological diagnosis is unknown
7. DIFFERENTIAL DIAGNOSIS – Other causes to consider
The differential diagnosis of paraplegia with incontinence is broad. The physician must quickly rule out life-threatening or permanently paralyzing causes:
Table: Systematized differential diagnosis
| Cause | Distinctive signs | Key investigation |
| Malignant spinal cord compression | Known cancer, spinal pain, subacute onset | Urgent spine MRI |
| Massive disc herniation | Work-related injury, acute onset, average age | Lumbosacral MRI |
| Epidural abscess | Fever + spinal pain + rapid loss | MRI with contrast, blood cultures |
| Epidural hematoma | Anticoagulants, sudden onset, brutal pain | Urgent MRI |
| Pathological vertebral fracture | Minor trauma in osteoporotic or cancer patients | X-ray + CT of the spine |
| Transverse myelitis | Young, rapid onset, no compressive injury | MRI + CSF |
| Multiple sclerosis | Young women, flare-ups, ocular symptoms | MRI + CSF oligoclonal bands |
| Guillain-Barré | Ascending, areflexia, post-infectious | EMG + CSF (albumin-cytological dissociation) |
| Multiple myeloma | Diffuse bone pain, anemia, proteinuria | Serum electrophoresis, MRI |
| Spinal cord infarction | Sudden onset (minutes), no changes on initial MRI | Diffusion MRI |
| Severe spinal stenosis | Elderly, neurogenic claudication, insidious onset | MRI + vascular evaluation |
| Spinal AV malformation | Fluctuating, aggravated by exertion, noise on auscultation | MRI + spinal angiography |
| Infectious spondylodiscitis | Fever, persistent spinal pain, elevated ESR/CRP | MRI + biopsy |
| Paraneoplastic syndrome | Known cancer, positive anti-neuronal antibodies | Serum onconeuronal antibodies |
8. THERAPY – How to treat paraplegia and incontinence
Treatment depends fundamentally on the identified cause and the speed of onset of neurological deficit. The basic principle: the earlier the intervention, the better the chances of neurological recovery.
8.1. Malignant spinal cord compression – emergency treatment
CORTICOSTEROIDS – first line, immediately upon clinical suspicion:
- Dexamethasone loading dose: 10 mg IV, followed by 16 mg/day in divided doses (4 mg every 6 hours)
- Mechanisms: reduces vasogenic edema, may improve medullary perfusion, relieves pain
- Do not wait for the MRI to initiate dexamethasone if the patient has neurological deficit!
RADIOTHERAPY – most commonly used, applicable to most patients:
- Standard doses: 30-40 Gy in 10 fractions (3-4 weeks)
- Single fraction: 8 Gy – for patients with severe prognosis or predominant pain
- Radiosensitive tumors (myeloma, lymphoma, breast cancer, prostate cancer) – excellent response
- Radioresistant tumors (RCC, melanoma, sarcoma) – require higher doses or SBRT
SBRT (Stereotactic Body Radiation Therapy) – the revolution of 2024-2026:
- Large, precise doses in 1-5 fractions
- Excellent for radioresistant tumors
- Local control 80-90% at 1-2 years
- Requires dedicated equipment and tertiary hospital
SURGERY – precise indications:
- Spinal instability (SINS score 13-18)
- Spinal cord compression with rapidly progressive neurological deficit (Bilsky grade 2-3)
- Unknown histological diagnosis
- Failure of previous radiotherapy
- Solitary metastasis with good control of systemic disease
Current approach (2026): Separations Surgery + SBRT
- Minimal surgery to create space between the tumor and the marrow
- Followed by high-dose SBRT (24-30 Gy in 3-5 fractions)
- Local control 84-93% at 1 year
CHEMOTHERAPY / SYSTEMIC THERAPY – for chemosensitive tumors:
- First line in lymphomas, leukemias, small cell lung cancer, germ cell tumors, hormone-sensitive breast cancer
- Targeted therapies (EGFR, ALK, BRAF inhibitors) for cancers with specific mutations and spinal metastases
8.2. Epidural abscess – infectious emergency
PRINCIPLE: Antibiotics + surgical or CT-guided drainage
Empirical antibiotic regimen (initiated IMMEDIATELY):
- Vancomycin 15-20 mg/kg IV every 8-12 hours (covers MRSA)
- PLUS Ceftriaxone 2g IV every 12h (gram-negatives)
- PLUS Metronidazole 500mg IV every 8 hours (anaerobes)
Emergency surgery – if there is neurological deficit:
- Decompressive laminectomy + abscess drainage
- Ideal in the first 24 hours after the onset of deficit
Duration of antibiotic therapy:
- 4-6 weeks (with proper drainage)
- 6-8 weeks if there is also vertebral osteomyelitis
⚠️ Crucial prognostic factor: The chances of complete recovery are excellent if treatment is initiated when symptoms are localized, before myelopathy sets in. If complete paralysis lasts more than 36-48 hours before decompression, recovery is unlikely.
8.3. Cauda equina syndrome – disc emergency
Emergency surgery (lumbar discectomy) within the first 24-48 hours of onset:
- Restoring sphincter control depends on the speed of intervention
- The longer preoperative incontinence lasts, the lower the chances of recovery.
Corticosteroids – useful as a preoperative bridge
8.4. Severe spinal stenosis with myelopathy
Conservative (in the absence of severe deficits):
- Physical Therapy
- Epidural corticosteroid injections
- Short-term anti-inflammatory drugs (NSAIDs)
- Gabapentin/pregabalin for neuropathic pain (limited efficacy in lumbar stenosis)
Surgical:
- Decompressive laminectomy (standard)
- Minimally invasive techniques (endoscopic, tubular)
- Spinal fusion – ONLY if there is documented instability
- Interspinous devices (X-STOP) for selected cases
8.5. Management of urinary and fecal incontinence
In the immediate term:
- Indwelling urinary catheter – prevents bladder bloat (urinary retention) and urinary tract infections
- Intermittent catheterization – for patients with neurological urinary retention
- Bowel regimen – laxatives, enemas (microlax, bisacodyl suppositories)
Long-term (neuromodulation, recovery):
- Bladder reeducation under the guidance of a continence specialist
- Perineal physiotherapy (Kegel exercises)
- Sacral neuromodulation (for selected cases)
- Psychological counseling (the impact of incontinence on quality of life is major)
8.6. Pain management
Spinal cord compression pain often has multiple components:
- Somatic (from bone, periosteum) – NSAIDs, opioids (morphine, oxycodone)
- Neuropathic (from damaged nerves) – amitriptyline, gabapentin, pregabalin, duloxetine
- Radiotherapy as an analgesic agent – extremely effective for bone metastases
9. ALARM SIGNS – When should you go to the emergency room immediately?
🚨 Go to the emergency room IMMEDIATELY if you have any of the signs below:
| Alarm sign | What can it indicate? |
| 🔴 Sudden onset or rapid worsening of leg weakness | Spinal cord compression, epidural abscess, hematoma |
| 🔴 Loss of bladder or bowel control (incontinence or inability to urinate/defecate) | Cauda equina syndrome or spinal cord compression |
| 🔴 Numbness or lack of sensitivity in the genital, perineal or gluteal area (“saddle”) | Cauda equina syndrome |
| 🔴 Intense spinal pain with fever | Epidural abscess or spondylodiscitis |
| 🔴 In the cancer patient: any new or rapidly worsening spinal pain | Vertebral metastases, spinal cord compression |
| 🔴 Brutal spinal pain in an anticoagulated patient | Epidural hematoma |
| 🔴 Rapid progression of deficit (hours!) | Any emergency surgical cause |
| 🟠 Spinal pain that worsens in supine position, at night | Bone metastases |
| 🟠 Spinal pain in a patient with osteoporosis after minor trauma | Osteoporotic/pathological fracture |
10. PROPHYLAXIS – What can we do for prevention?
10.1. In the cancer patient
- imaging monitoring (bone scintigraphy, PET-CT, MRI) for early detection of vertebral metastases – before compression occurs
- Bisphosphonates or denosumab (Zometa/Xgeva) – reduce the risk of skeletal events in patients with bone cancer
- Correction of bone fragility – calcium, vitamin D, treatment of osteoporosis induced by oncological treatment
- Prophylactic radiotherapy – on asymptomatic vertebral metastases before compression occurs
- Kyphoplasty/vertebralplasty – cement injected into the fractured/threatened vertebra, reduces the risk of collapse
10.2. Epidural abscess prophylaxis
- Strict asepsis precautions for spinal procedures (infiltrations, epidural catheters)
- Rigorous monitoring of epidural catheters (daily skin inspection)
- Optimal glycemic control in diabetics
- Perioperative antibiotic therapy
10.3. Lifestyle and degenerative prevention
- Maintaining normal body weight
- Regular exercises to strengthen the paravertebral and abdominal muscles
- Correct ergonomics at work
- Avoiding repeated spinal trauma
- Quitting smoking (affects intervertebral discs)
- Vitamin B12 supplementation (deficiency can cause myelopathy)
11. Implications in therapy: what does it practically mean for the patient?
The most important message: Neurological prognosis is directly proportional to the speed with which spinal cord compression or cauda equina syndrome is diagnosed and treated.
The golden rule in oncological spinal cord compression:
- Ambulatory patients (able to walk) at the time of diagnosis → 80% remain ambulatory after treatment
- Patients with paresis (weakness, but not complete paralysis) → variable recovery , depends on the speed of intervention
- Patients with complete paralysis that has been present for more than 24-48 hours → unlikely recovery
What does it practically mean for you as a patient:
- Don’t ignore spinal pain if you have or have had cancer.
- Don’t blame sudden leg weakness on “fatigue” or “age”
- Any new bladder or bowel problem in a cancer patient is a medical emergency.
- Be proactive: talk to your oncologist about your spine condition at every consultation
Frequently Asked Questions (FAQ)
❓ If I have cancer and back pain, does it mean I have metastases? Not necessarily. Back pain is very common and has dozens of causes. But in a patient with cancer, especially in types that frequently metastasize to the bone (breast, prostate, lung, myeloma), persistent spinal pain, especially nocturnal or that does not improve with rest, requires urgent imaging evaluation.
❓ Can I regain bladder control if I have lost it? It depends on the cause and the speed of treatment. If the compression is treated quickly (within the first 24-48 hours), there is a real chance of recovery. If the paralysis has been complete for longer, recovery is less likely, but partial recovery remains possible with physical therapy.
❓ I am on anticoagulant treatment and have sudden back pain – what do I do? Go to the emergency room immediately. Anticoagulants can cause epidural hematoma – a neurosurgical emergency with a therapeutic window of hours.
❓ What does it mean if the MRI shows “T6 compression”? It means that at the level of the 6th thoracic vertebra (mid-back), the spinal cord is compressed. Deficits may include weakness in both legs, sensory changes below the T6 level, and possible bladder problems. Urgent multidisciplinary evaluation is required.
❓ How much can symptoms be improved with radiotherapy? Radiotherapy relieves pain in ~80% of patients and can stabilize or improve motor deficits, especially in radiosensitive tumors. The analgesic effect occurs in 2-4 weeks; the neurological effect depends on the degree of compression.

| 🔴 COMPLETE paralysis more than 24-48 hours before treatment | Low – full recovery is unlikely | Late intervention |
| 🔴 COMPLETE paralysis for more than 48 hours without treatment | Very low – less than 30% regain walking | |
| ✅ Epidural abscess treated BEFORE neurological deficit | excellency | Early diagnosis |
| ⚠️ Abscess treated AFTER neurological deficit develops >36-48 hours | low | Drainage emergency |
🏥 TABLE 8 – Simplified differential diagnosis (how to distinguish the causes)
| If you have… | Think about… | Key investigation |
| Known cancer + new back pain | Vertebral metastases, spinal cord compression | URGENT full spine MRI |
| Low back pain + saddle-shaped numbness + sudden incontinence | Cauda equina syndrome | Lumbosacral MRI EMERGENT |
| Fever + spinal pain + neurological deficit | Epidural abscess | MRI with contrast + blood cultures |
| Anticoagulants + brutal back pain + rapid paralysis | Epidural hematoma | EMERGENCY MRI + reversal of anticoagulants |
| Elderly + unsteady gait + progressive weakness + gradual incontinence | Severe spinal stenosis with myelopathy | Spine MRI + vascular evaluation |
| Young + rapid weakness in legs + sensitive level + no trauma | Transverse myelitis | MRI + CSF exam |
| Weakness ascending from the feet upwards + areflexia + post-infection | Guillain-Barré | EMG + CSF (elevated proteins, no cells) |
| Multiple sneezes + young people + ocular symptoms + repeated episodes | Multiple sclerosis | MRI brain + spine + CSF oligoclonal bands |
| Sudden onset within minutes + violent pain + no trauma | Spinal cord infarction | Diffusion MRI of the spine, CT of the aorta |
| Bone cancer + vertebral compression fracture + osteoporosis + minor trauma | Pathological fracture | Rx + spine CT + bone scintigraphy |
💊 TABLE 9 – Management of urinary and fecal incontinence (practical)
| Phase | Problem | Practical solution | Who applies it? |
| Immediately (hospital) | Inability to urinate (retention) | Internal urinary catheter – prevents painful bladder infection | Medical team |
| Immediately (hospital) | Fecal incontinence | Micro-enemas (Microlax), Dulcolax suppositories, bowel regimen | Medical team + caregiver |
| short term | Neurogenic bladder | Intermittent catheterization 4-6 times/day | Educated patient or caregiver |
| Long term | Bladder reeducation | Specialized program with a physiotherapist specializing in continence | Urologist + physiotherapist |
| Long term | Sphincter exercises | Daily Kegel exercises | The patient alone, with guidance |
| Severe cases | Permanent neurogenic incontinence | Sacral neuromodulation (implanted device) | Urologist surgeon |
| All stages | Psychological impact (shame, isolation) | Psychological counseling, support groups | Oncologist psychologist |
📋 TABLE 10 – Checklist for the cancer patient: essential questions for the doctor
| # | Ask the oncologist | Why is it important? |
| 1 | “I have new back pain – should I get a spinal MRI?” | Spinal pain in cancer patients is an URGENT until proven otherwise |
| 2 | “My back pain is worse at night or when lying down – what does this mean?” | Classic sign of vertebral metastases/incipient compression |
| 3 | “Does my cancer frequently metastasize to the spine?” | Helps you know if you are in a risk group (breast, prostate, lung, myeloma) |
| 4 | “If I feel weakness in my legs or bladder problems, what number do I call?” | Emergency preparedness – knowing exactly what to do |
| 5 | “Can I take bisphosphonates or denosumab to protect my bones?” | Medications that reduce the risk of fracture and spinal cord compression |
| 6 | “The MRI shows that the tumor is close to the marrow – what do we do preventively?” | Prophylactic radiotherapy before compression = much more effective |
| 7 | “What physical therapy can I do for my spine?” | Preventing muscle weakness and instability |
| 8 | “What does the SINS score on my imaging report mean?” | Spinal instability score indicating fracture risk |
🔄 TABLE 11 – Prophylaxis: What can we do for prevention?
| Category | Preventive measure | For whom |
| Cancer patient | Periodic spine MRI for early detection of metastases | Cancers with bone risk: breast, prostate, lung, myeloma, renal |
| Cancer patient | Bisphosphonates (Zoledronic Acid) or Denosumab monthly | Patients with confirmed bone metastases |
| Cancer patient | Prophylactic radiotherapy on asymptomatic metastases | When MRI shows metastases, BEFORE symptoms appear |
| Cancer patient | Kyphoplasty/vertebralplasty on threatened vertebrae | Vertebrae at risk of compression, before fracture |
| Patient with epidural catheter | Daily inspection of the skin around the catheter, strict asepsis | Any patient with an indwelling epidural catheter |
| Diabetic patient | Optimal glycemic control | Increased risk of epidural abscess |
| Everyone | Paravertebral muscle strengthening exercises | Preventing disc degeneration and stenosis |
| Everyone | Quitting smoking | Smoking accelerates disc degeneration |
| Everyone | Maintaining normal weight | Obesity accelerates spinal stenosis |
| Everyone | Vitamin B12 supplementation | Deficiency can cause myelopathy |
