Transient encephalopathy in a postoperative non-alcoholic female with Marchiafava-Bignami disease.

Marchiafava-Bignami disease (MBD) is historically reported in middle-aged alcoholic men. We describe the presentation, course and radiological findings of a young non-alcoholic woman who developed encephalopathy and MRI findings consistent with MBD postoperatively. She returned to baseline after vitamin supplementation. We believe it is important to diagnose MBD because it is a potentially reversible encephalopathy.
