Cavernous angiomas of the internal auditory canal (IAC) are rare. They are angiographically occult; and because the clinical symptoms are similar both in intracanalicular cavernous angiomas and acoustic tumors it had been difficult to differentiate pre-operatively both of these pathologies until the advent of magnetic resonance imaging (MRI). Even nowadays the correct diagnosis may be missed if the patient is imaged only with gadolinium enhanced MRI without prior obtaining a non-contrast MRI. These diagnostic difficulties are illustrated by the report of a related case. The importance of thorough neuroradiological investigations stressed and MRI features, surgical management and relevant literature concerning the cavernous angiomas of the internal auditory canal are discussed.
内耳道海绵状血管瘤较为罕见。它们在血管造影上表现隐匿；而且由于管内海绵状血管瘤和听神经瘤的临床症状相似，在磁共振成像（MRI）出现之前，术前很难区分这两种病变。即使在如今，如果仅对患者进行钆增强MRI成像而未事先进行非增强MRI成像，仍可能漏诊。一例相关病例报告说明了这些诊断困难。强调了全面神经放射学检查的重要性，并讨论了内耳道海绵状血管瘤的MRI特征、手术治疗及相关文献。
