Spontaneous Cure Of Dural Arteriovenous Malformation In The Posterior Fossa
Surgical Neurology 12(2): Aug 1979; 111-114
View Original Source →Abstract
A 28-year-old male with spontaneous disappearance of dural arteriovenous malformation in the posterior fossa ten years after onset is reported. Ligation and excision of the right occipital artery brought about no marked changes in clinical manifestations and the postoperative angiogram. Over nine years after the operation, pulsatile tinnitus disappeared suddenly without any obvious cause and the dural arteriovenous malformation was absent on the angiogram. The frequency of such an occurrence and some possible mechanisms involved are reviewed and discussed.
