A case of a rare arteriovenous malformation in the internal auditory canal is reported. It caused unilateral tinnitus, facial weakness, trigeminal hypesthesia, and vertigo with lateropulsion. The audiological and otoneurological findings together with air-cisternography a CT scan had indicated an intrameatal tumor. An extended trans-temporal exposure of the internal auditory canal demonstrated an angiomatous lesion compressing the adjacent seventh and eighth cranial nerves. It could be removed safely by a second-stage lateral suboccipital approach to the cerebello-pontine angle.
报告了一例内耳道罕见动静脉畸形病例。它导致单侧耳鸣、面部无力、三叉神经感觉减退以及伴有向一侧倾倒的眩晕。听力学和耳神经学检查结果以及气脑池造影CT扫描显示为耳道内肿瘤。对内耳道进行扩大的经颞部暴露显示一个血管瘤样病变压迫相邻的第七和第八颅神经。通过二期枕下外侧入路至桥小脑角可安全切除该病变。
