Spontaneous disappearance of a spinal dural arteriovenous fistula.

Abstract

A case of proved regression of an asymptomatic dural arteriovenous fistula is reported. At the time of diagnosis, myelography showed dilated perimedullary veins. Angiography demonstrated a radicular outflow from these veins to the epidural plexus. A follow-up angiogram 5 years later was normal.
