A 66-year-old male was admitted to our hospital with complaints of sudden hearing loss in his right ear and vertigo. The patient had a history of hypertension and diabetes mellitus. No other neurological deficits were noted. Neurootological examinations revealed sensorineural hearing loss and a horizontal gaze nystagmus. Right facifal and trigeminal nerve paralysis appeared 5 days later. CT and MR' examinations revealed a lesion, suggesting an infarction in the region of the anterior inferior cerebellar artery (AICA). Infarction of the AICA should therefore be considered in patients at risk for arteriosclerosis who present with a sudden hearing loss and vertigo.
