전하 소뇌 동맥 경색과 돌발성 난청을 유발한 뇌바닥 동맥의 확장성 동맥병증 1예

Dolichoectasia describes enlarged, tortuous, and dilated arteriopathy which mainly involves vertebral and basilar arteries. Clinical expression includes from asymptomatic to malignant disease like infarction and intracranial bleeding. Anterior inferior cerebellar artery infarction is rare disease and can cause sudden deafness, vertigo, facial palsy, tinnitus, ipsilateral gaze palsy, loss of facial thermal sense, ipsilateral Horner’s syndrome, and cerebellar ataxia. Sudden deafness without central symptoms is rare manifestation of anterior inferior cerebellar artery infarction. We experienced a case of sudden deafness caused by anterior inferior cerebellar artery infarction secondary to basilar artery dolichoectasia. (J Clinical Otolaryngol 2010;21:245–248)
