He lost suddenly right hearing 2 months ago, but he didn't his sudden sensori neural hearing loss (SSNHL). He had left SSNHL 1 day ago, he visited Jeju National University Hospital. He only complained of hearing loss. In pure tone audiometry (PTA), his hearing was measured 62dB/24% at right side and 87dB/0% at left side respectively. The magnetic resonance image (MRI) and angiography (MRA) of the brain showed total occlusion of right internal carotid artery and both anterior inferior cerebellar artery (AICA) was invisible in MRA. There was no AICA infarction in diffusion image of brain MRI. We treated him with high dose methylprednisolone, intratympanic dexamethasone injection (ITDI), IV alprostadil 10pg, ginkobiloba, pentoxifyline and aspirin.
