VHOSPITAL.CLINIC · Differential Diagnosis
Multiple Sclerosis vs Transverse Myelitis
Clinical comparison — shared symptoms, key differences, distinguishing diagnostic tests, treatment pathways, and when to seek urgent evaluation.
Condition Overview
Condition A
Multiple Sclerosis
Multiple sclerosis is a chronic autoimmune disease in which the immune system attacks the myelin sheath of nerve fibers in the central nervous system. It causes episodes of neurological symptoms including vision loss, muscle weakness, balance problems, and cognitive changes.
Condition B
Transverse Myelitis
Transverse myelitis is inflammation across both sides of the spinal cord, causing weakness, sensory changes, and bladder dysfunction below the level of inflammation. It can be idiopathic or associated with multiple sclerosis or neuromyelitis optica.
Shared Symptoms — Why They're Confused
Both conditions present with 2 overlapping symptoms, making clinical differentiation essential.
Key Clinical Differences
Multiple Sclerosis
- Relapsing-remitting course with multiple CNS lesions in time and space
- Optic neuritis, internuclear ophthalmoplegia, trigeminal neuralgia
- White matter lesions on MRI brain AND spinal cord
- CSF oligoclonal bands in 85-95%
Transverse Myelitis
- Acute or subacute onset of spinal cord dysfunction
- Sensory level, paraparesis, bladder dysfunction
- Single lesion spanning ≥3 vertebral segments (longitudinally extensive)
- May be isolated or first presentation of MS/NMO
Distinguishing Diagnostic Tests
| Test | Multiple Sclerosis | Transverse Myelitis |
|---|---|---|
| MRI brain + spine | Multiple periventricular lesions (Dawson's fingers), short cord lesions | Longitudinally extensive cord lesion ≥3 segments; few or no brain lesions |
| AQP4-IgG (NMO antibody) | Negative — MS does not have AQP4 antibody | Positive in NMOSD — changes prognosis and treatment |
| CSF analysis | Oligoclonal bands (unique to CNS); mild lymphocytosis | Pleocytosis may be marked; oligoclonal bands less common in isolated TM |
Treatment Approaches
Multiple Sclerosis
- •Disease-modifying therapies: interferon-beta, glatiramer, natalizumab, ocrelizumab
- •IV methylprednisolone for relapses
Transverse Myelitis
- •High-dose IV methylprednisolone
- •Plasma exchange for refractory cases
- •Treat underlying cause (NMOSD, SLE, infection)
When Doctors Consider Each Diagnosis
🔵 Consider Multiple Sclerosis when:
- →Multiple lesions in time and space, optic neuritis, oligoclonal bands, short cord lesions
🟢 Consider Transverse Myelitis when:
- →Single extensive cord lesion, sensory level, AQP4 positive, no brain lesions
