[Chronic spontaneous lumbar epidural hematoma].

We report an exceptional case of cauda equina syndrome, caused by a chronic epidural hematoma of the lumbar spine, (L2-L3). A 53 year old man without history of trauma, lumbar punctures or antiagregant medication, suffered from progressive back pain and minor motor deficit in the legs. The etiology, MRI, intraoperative findings and microscopical study are presented and discussed. After surgery there was a complete resolution of the clinical picture.
