We report a case of an arteriovenous malformation within the internal auditory meatus and cerebellopontine angle, and we discuss its imaging appearances and management.
A 50-year-old man presented with a two-year history of vertigo. Magnetic resonance imaging and magnetic resonance angiography demonstrated a lesion consisting of multiple 'high flow' vessels within the left internal auditory meatus and cerebellopontine angle. Transarterial embolisation was performed, with obliteration of the arteriovenous malformation.
Arteriovenous malformations of the internal auditory meatus and cerebellopontine angle are exceedingly rare. It is important that a pre-treatment diagnosis is made, as the management of arteriovenous malformation differs from that of other, more common lesions at this site.
我们报告一例内耳道及桥小脑角区动静脉畸形病例，并讨论其影像学表现及治疗方法。
一名50岁男性，有两年眩晕病史。磁共振成像及磁共振血管造影显示左侧内耳道及桥小脑角区有一由多条“高流量”血管组成的病变。进行了经动脉栓塞治疗，动静脉畸形闭塞。
内耳道及桥小脑角区动静脉畸形极为罕见。进行治疗前诊断很重要，因为动静脉畸形的治疗与该部位其他更常见病变的治疗不同。
