Tumor types other than acoustic neuromas are uncommonly encountered in the cerebellopontine angle, and unusual lesions limited to the internal auditory canal (IAC) are given more rare. We present five patients with unusual tumors of the IAC including two meningiomas, two arachnoid cysts, and a hemangioma. These unusual tumors, and lipomas, are discussed. Particular attention is paid to the pathophysiology of the lesions and treatment recommendations. The differential diagnosis of intracanalicular lesions using magnetic resonance imaging is also presented.
除听神经瘤外，其他肿瘤类型在桥小脑角很少见，局限于内耳道（IAC）的异常病变则更为罕见。我们报告了5例患有IAC异常肿瘤的患者，包括2例脑膜瘤、2例蛛网膜囊肿和1例血管瘤。本文讨论了这些异常肿瘤以及脂肪瘤。特别关注病变的病理生理学和治疗建议。还介绍了使用磁共振成像对管内病变进行鉴别诊断的方法。
