A cerebellar infarction case demonstrating sensorineural hearing loss and vertigo

Abstract

Sudden idiopathic sensorineural hearing loss is a frequent diagnosis in cases of acute hearing loss and vertigo. On rare occasions, however, these symptoms in a patient are caused by a cerebrovascular disorder. We describe a patient with hearing loss and vertigo associated with cerebellar infarction. A 68-year-old male with atrial fibrillation and hypertension complained of sudden hearing loss in his right ear and vertigo without any other neurological deficits. The neuro-otological examination revealed severe sensorineural hearing loss, gaze nystagmus, and a saccadic pattern in the eye tracking test. MRI showed an anterior inferior cerebellar territory infarction.
