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.
