Osteomas of the internal auditory canal are rare lesions, with only 12 reported cases in the world literature. Symptoms are those of eighth nerve compression, and include unilateral hearing loss and vestibular weakness, thus mimicking symptoms of acoustic neuroma. We report a patient with an osteoma of the internal auditory canal, along with a review of the literature. We note age and sex characteristics from the literature, give evidence of localized trauma as a possible etiologic factor for this lesion, and discuss the pitfalls of relying exclusively on magnetic resonance imaging in the workup of suspected retrocochlear lesions.
内耳道骨瘤是一种罕见的病变，世界文献中仅报道了12例。症状为第八神经受压的症状，包括单侧听力丧失和前庭功能减弱，因此与听神经瘤的症状相似。我们报告了一例内耳道骨瘤患者，并对文献进行了综述。我们从文献中指出年龄和性别特征，提供局部创伤作为该病变可能病因的证据，并讨论在疑似蜗后病变的检查中单纯依靠磁共振成像的陷阱。
