Emergency Neurological Assessment and Management
This patient requires immediate emergency evaluation for acute neurological compromise, with urgent MRI/CT imaging of the brain and spine within hours, not days, as progressive bilateral weakness with sensory changes suggests a rapidly evolving spinal cord or peripheral nerve emergency that threatens permanent disability if not diagnosed and treated emergently.
Immediate Clinical Priority: Rule Out Life-Threatening Neurological Emergencies
This presentation—progressive weakness preventing ambulation, bilateral extremity numbness and tingling, arm weakness, plus axial pain (ribs/pelvis)—demands urgent consideration of:
Critical Differential Diagnoses Requiring Emergency Action
- Guillain-Barré Syndrome (GBS): Ascending paralysis with sensory symptoms can progress to respiratory failure within hours 1
- Acute spinal cord compression: From epidural abscess, hematoma, tumor, or vertebral fracture/dislocation causing bilateral symptoms 1
- Transverse myelitis: Inflammatory spinal cord lesion causing bilateral motor/sensory deficits 1
- Acute stroke/brainstem infarction: Bilateral symptoms suggest posterior circulation involvement requiring immediate imaging 1
The 4-6 hour window for tissue viability applies not just to limb ischemia but also to spinal cord ischemia—delayed diagnosis can result in permanent paralysis 1.
Immediate Bedside Assessment (Within Minutes)
Motor Function Evaluation
- Test strength in all four extremities systematically: Grade 0-5 power in proximal and distal muscle groups 1
- Assess ability to stand/walk independently: Complete inability to walk indicates severe motor compromise requiring emergency intervention 1
- Check for ascending pattern: Progressive weakness moving from legs to arms suggests GBS 1
Sensory Examination
- Map sensory level precisely: A clear dermatomal level suggests spinal cord pathology 1
- Distinguish between peripheral neuropathy vs. myelopathy: Stocking-glove pattern vs. sensory level 1
Respiratory Assessment (Critical in GBS)
- Measure vital capacity and negative inspiratory force: Declining respiratory function requires ICU admission and possible intubation 1
- Monitor for bulbar symptoms: Dysphagia, dysarthria indicate brainstem involvement 1
Reflexes and Pathological Signs
- Check deep tendon reflexes: Areflexia suggests GBS; hyperreflexia with Babinski sign suggests upper motor neuron lesion 1
Emergency Diagnostic Workup (Within 1-2 Hours)
Neuroimaging—Absolute Priority
- MRI of entire spine with and without contrast: Gold standard for spinal cord compression, transverse myelitis, epidural abscess 1
- Brain MRI with diffusion-weighted imaging: If stroke suspected based on acute onset or brainstem signs 1
- If MRI unavailable or contraindicated: CT myelography for spinal pathology 1
Laboratory Studies
- Complete blood count with differential: Infection, malignancy screening 2
- Comprehensive metabolic panel: Electrolyte abnormalities, renal function 2
- Creatine kinase: Elevated in rhabdomyolysis from prolonged immobility 1
- Inflammatory markers (ESR, CRP): Elevated in inflammatory/infectious myelopathy 1
Specialized Testing Based on Clinical Suspicion
- Lumbar puncture with CSF analysis: If GBS or transverse myelitis suspected—check protein (elevated in GBS), cell count, oligoclonal bands 1
- Nerve conduction studies/EMG: Can confirm GBS but should NOT delay treatment if clinical suspicion high 1
Immediate Management Algorithm
If Spinal Cord Compression Identified
- Immediate neurosurgical consultation: Surgical decompression within 24 hours improves outcomes 1
- High-dose IV corticosteroids: Dexamethasone 10 mg IV bolus, then 4 mg every 6 hours if tumor-related 1
- Emergent antibiotics if epidural abscess: Vancomycin plus ceftriaxone plus metronidazole before drainage 1
If Guillain-Barré Syndrome Suspected
- ICU admission for respiratory monitoring: Vital capacity <20 mL/kg or rapidly declining requires intubation 1
- Intravenous immunoglobulin (IVIG) 0.4 g/kg/day for 5 days: First-line treatment, start immediately 1
- Alternative: Plasma exchange: If IVIG contraindicated or unavailable 1
- Do NOT use corticosteroids: Ineffective in GBS and may worsen outcomes 1
If Acute Stroke/TIA Suspected
- Immediate vascular neurology consultation: Patients with bilateral symptoms within 48 hours are VERY HIGH risk for recurrent stroke 1
- Brain and vascular imaging (CTA/MRA from aortic arch to vertex) within 24 hours: Required for high-risk presentations 1
- Dual antiplatelet therapy: Aspirin plus clopidogrel if ischemic stroke confirmed 1
If Transverse Myelitis Suspected
- High-dose IV methylprednisolone: 1 gram daily for 3-5 days 1
- Screen for underlying causes: Multiple sclerosis, neuromyelitis optica, systemic lupus erythematosus 1
Critical Pitfalls to Avoid
Do Not Delay Imaging for Laboratory Results
- Neuroimaging must occur within hours, not after "routine" lab workup 1. The longer spinal cord compression persists, the less likely functional recovery becomes 1.
Do Not Assume "Peripheral Neuropathy" Without Imaging
- Bilateral symptoms with inability to walk suggest central pathology until proven otherwise 1. Diabetic neuropathy does not cause acute inability to ambulate 1.
Do Not Wait for Neurology Consultation to Order Imaging
- Emergency physicians should order urgent MRI spine immediately upon recognizing this presentation 1. Consultation can occur simultaneously with imaging 1.
Do Not Discharge with "Follow-Up Outpatient"
- This presentation requires hospital admission for continuous monitoring and definitive diagnosis 1. Progressive neurological deficits can deteriorate rapidly, including respiratory failure in GBS 1.
