Isolated sudden hearing loss with vertigo is usually peripheral origin. We report two cases with anterior inferior cerebellar artery infarction (AICA) manifesting sudden hearing loss with vertigo as an isolated symptom. Patient 1 was a 64-year-old man presented with right sided sudden hearing loss and vertigo accompanying horizontal beating nystagmus to the left. He had no other neurologic symptoms. MRI showed right AICA infarction involving lateral pons and middle cerebellar peduncle. Patient 2 was a hypertensive 56-year-old man. Left sided sudden hearing loss with vertigo was as an initial manifestation. Two days later, left sided facial palsy developed and MRI showed acute infarction in left lateral pons, middle cerebellar peduncle, and cerebellum. AICA infarction can be presented the hearing loss and vertigo as an isolated symptom and mimic the syndrome of peripheral origin.
