背景听神经瘤占桥小脑角肿瘤的80%。副神经节瘤是一种罕见的肿瘤在这个地区。目的报告1例起源于小脑前下动脉的桥小脑角副神经节瘤。结果该肿瘤的临床及影像学表现与神经瘤无明显区别，仅术中表现为血管瘤。组织病理学确诊。结论这一独特的副神经节瘤的位置可以用现有的胚胎学资料来解释。内镜辅助下的最小乙状窦后入路可以安全、完整地切除肿瘤。
Background Acoustic neuroma account for 80% of cerebellopontine angle tumors. Paraganglioma is a rare tumor in this region. Objective The authors report a case of cerebellopontine angle paraganglioma arising from the anterior inferior cerebellar artery. Results The clinical and radiologic features were indistinguishable from those of a neuroma, and only the intraoperative view showed a vascular tumor. Definitive diagnosis was made by histopathologic methods. Conclusions This unique paraganglioma location may be explained by existing embryologic data. The minimal retrosigmoid approach, assisted by endoscopy, allows safe and complete removal of the tumor.
