Spontaneous Disappearance of a Cerebral Arteriovenous Malformation: —Case Report—

Abstract

A 63-year-old male presented with a cerebral arteriovenous malformation in the dominant motor area which subsequently disappeared spontaneously. He had suffered from epileptic attacks in his right extremities for 2 years before he first presented aged 53 years. He was treated with anticonvulsants and was followed up. Bleeding from the cerebral arteriovenous malformation occurred when he was 61 years old. Two years later, angiography revealed the complete disappearance of the cerebral arteriovenous malformation. Such spontaneous disappearance is rare, and the patient should be fol lowed up as the nidus may reappear later. © 1996, The Japan Neurosurgical Society. All rights reserved.
