Sudden sensorineural hearing loss (SNHL) develops usually in unilateral ear without known etiology. In contrast, bilateral sudden SNHL is mostly related to serious systemic diseases and have a severe hearing loss and poor prognosis compared than unilateral one. We describe here a 59-year-old man presented with a bilateral sudden SNHL and vertigo possibly attributed to dolichoectasia in vertebrobasilar artery, and discuss the possible mechanism.

AbstractAbstract PDF
Sudden hearing loss and vertigo are the typical presentation of anterior inferior cerebellar artery infarction, but may rarely occur in posterior inferior cerebellar artery (PICA) infarction. Here we describe a 65-year-old man who presented with sudden hearing loss in his left ear and severe vertigo. The diffusion-weighted magnetic resonance imaging revealed acute infarction in the territory of PICA and cerebral angiography showed non-visualization of left vertebral artery. Sudden hearing loss and vertigo may be a presentation of PICA infarction.
