RESUMO
A 58-year-old woman experienced relapsing acute longitudinally extensive transverse myelitis that developed rapidly in 3 days after lumbar surgery. The patient had a history of systemic lupus erythematosus with acute transverse myelitis and had undergone plasmapheresis 16 years ago. New neurologic deficits including paraplegia of the lower limbs, sensory alterations, and bowel incontinence presented 3 days postoperatively. Magnetic resonance imaging revealed a long-segment hyperintense signal over the thoracic spine on T2-weighted imaging. Intravenous pulse therapy with high-dose corticosteroid was first used for 5 days but was ineffective. Plasmapheresis after pulse therapy resulted in improved neurologic deficit. The patient then underwent 6 months of rehabilitation therapy but was partially wheelchair bound. She no longer had bladder and bowel incontinence.
