Four-year follow-up of a case of acute multiple sclerosis of the Marburg type.

We describe the clinical course, treatment and magnetic resonance findings during a four-year follow-up of a patient with acute multiple sclerosis of the Marburg type, treated with steroid and mannitol therapy, who survived the first bout. Although the course of the disease was clinically indistinguishable from relapsing-remitting multiple sclerosis, our case was characterized by peculiar features. These included the need for protracted steroid therapy and the remarkable tendency of MRI lesions to resolve completely.
