Abstract:
A sudden hearing loss with vertigo may originate from vascular insufficiency and sometimes presents as a prodrome of anterior inferior cerebellar artery infarction. Here we describe the case of a 48-year-old male patient who presented with a sudden onset of hearing loss in his right ear and severe, whirling type dizziness without associated neurological signs or symptoms. The diffusion-weighted magnetic resonance imaging (MRI) was normal on initial presentation, but 4 weeks after the onset of symptoms, the patient developed ipsilateral facial paralysis and dysarthria. A follow-up MRI revealed acute infarction in the territory of the anterior inferior cerebellar artery, involving the right lateral pons, right middle cerebellar peduncle, and inferolateral cerebellum.
