The most frequent lesion identified at the cerebellopontine angle cistern and internal auditory meatus (IAM) is the vestibular schwannoma. Radiological features, the role of imaging in screening and follow-up, therapeutic approaches and appearances following treatment will be discussed. Other cerebellopontine angle lesions will be illustrated and an algorithm presented to help in the imaging differential diagnosis. Whilst lesions other than vestibular schwannomas are rarely isolated to the IAM, the key clinical and radiological features that should raise the possibility of alternative neoplastic and inflammatory diseases will be highlighted.
最常见于桥小脑角池和内听道 (IAM) 的病变是前庭神经鞘瘤。本文将讨论其影像学特征、筛查和随访中的作用、治疗方法以及治疗后的表现。还将举例说明其他桥小脑角病变，并提供一个算法来帮助进行影像学鉴别诊断。虽然除了前庭神经鞘瘤以外的病变很少单独累及 IAM，但本文将重点介绍可能提示其他肿瘤和炎症性疾病的关键临床和影像学特征。
