Teratomata of the cerebellopontine angle are rare. A case of a lipoma of this localization occurring in a 50-year-old man with an interesting case history is reported. The differential diagnosis of tumours of the internal auditory meatus and the surrounding structures is discussed. In cases with an uncharacteristic clinical history suggesting involment of the VIIIth cranial nerve, it is important to focus attention on the existence of rare lesions of the internal acoustic porus. The diagnosis can only be established with operation and biopsy.
桥小脑角畸胎瘤很罕见。本文报告一例发生于一名50岁男性的该部位脂肪瘤，并伴有有趣的病史。文中讨论了内耳道及周围结构肿瘤的鉴别诊断。对于临床病史不典型、提示累及第八颅神经的病例，关注内耳道罕见病变的存在很重要。诊断只能通过手术和活检来确立。
