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.
