Myelitis

Myelitis is inflammation of the spinal cord, often immune-mediated, infectious, or post-infectious. Clinical features include motor, sensory, and autonomic deficits, depending on lesion level. Pathophysiology involves immune-mediated demyelination and neuronal injury. Diagnosis relies on MRI, cerebrospinal fluid analysis, and exclusion of mimics. Management includes corticosteroids, plasma exchange, and supportive care; prognosis depends on severity and etiology.
