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 post-operative angiogram. Over nine years after that operation, pulsatile tinnitus disappeared suddenly without any obvious cause and the dural arteriovenous malforamation was absent on the angiogram. The frequency of such an occurrence and some possible mechanisms involved are reviewed and discussed.
报告了一名28岁男性，其硬脑膜动静脉畸形在发病十年后于后颅窝自发消失。结扎并切除右枕动脉后，临床表现及术后血管造影均无明显变化。该手术九年多后，搏动性耳鸣无明显原因突然消失，血管造影显示硬脑膜动静脉畸形消失。本文对这种情况的发生频率及一些可能的机制进行了回顾和讨论。
