A 42-year-old man with normal hearing presented with a long history of vertigo and tinnitus. CT scan showed large osteomata of the internal auditory canal. Magnetic resonance imaging (MRI) was normal. The osteomata were removed surgically via the retrosigmoid approach and examined histologically. His symptoms were abolished. As MRI has become the gold standard in the search for small acoustic tumours it is likely that symptomatic bony lesions, rare though they are, will be missed if MRI is the sole imaging modality. A review of the literature is included.
一名听力正常的42岁男性，有长期眩晕和耳鸣病史。CT扫描显示内耳道有大的骨瘤。磁共振成像（MRI）结果正常。通过乙状窦后入路手术切除骨瘤并进行组织学检查。他的症状消失了。由于MRI已成为筛查小听神经瘤的金标准，因此如果仅采用MRI作为唯一的成像方式，有症状的骨病变虽然罕见，但很可能会被漏诊。本文还包括文献综述。
