We report the case of a 37-year-old woman with a history of long-standing right-sided sensorineural hearing loss who presented with an acute onset of vertigo and ipsilateral facial palsy. A computed tomographic scan study showed a stenosis of the right internal auditory canal (IAC). Neither generalized skeletal disease nor bony tumors, which may cause the IAC stenosis, were evident. The IAC stenosis found in this patient may be due to congenital malformation. Inflammation, compression or ischemia in the stenosed IAC may have resulted in the vertigo and facial palsy. This is the only case that we are aware of in which IAC stenosis is accompanied by vertigo and facial palsy.
我们报告了一例37岁女性病例，该患者有长期右侧感音神经性听力损失病史，此次因急性发作的眩晕和同侧面瘫前来就诊。计算机断层扫描研究显示右侧内耳道（IAC）狭窄。未发现可能导致IAC狭窄的全身性骨骼疾病或骨肿瘤。该患者发现的IAC狭窄可能是由于先天性畸形。狭窄的IAC内的炎症、压迫或缺血可能导致了眩晕和面瘫。这是我们所知的唯一一例IAC狭窄伴有眩晕和面瘫的病例。
