We report on a 68-year-old male with a cerebellopontine angle tumor manifesting at the 8th cranial nerve and presenting histopathological features of a rhabdomyoma. A literature review revealed four reports of intracranial nerve rhabdomyoma, all of adult type and including one manifestation at the vestibular nerve. We present the first case of a fetal type extracardiac rhabdomyoma manifesting at a cranial nerve. Although rare, rhabdomyomas must be considered in the differential diagnosis of vestibular schwannomas.
我们报告了一例 68 岁男性患者,其小脑脑桥角肿瘤表现为第 8 颅神经,并呈现出横纹肌瘤的组织病理学特征。文献回顾显示有 4 例颅内神经横纹肌瘤的报告,均为成人型,包括一例前庭神经表现。我们呈现了首例胎儿型心脏外横纹肌瘤表现为颅神经的病例。虽然罕见,但在鉴别诊断前庭神经鞘瘤时必须考虑到横纹肌瘤。
