摘要

A 57-year-old male patient was diagnosed with a left cerebellar infarction. He initially presented with unilateral sudden sensorineural hearing loss (SNHL) with long-lasting vertigo and spontaneous nystagmus to the left side, which were diagnosed using vestibular functional test tools and magnetic resonance imaging (MRI). MRI of the brain showed infarction in the area of the anterior and posterior cerebellar artery (AICA and PICA). Therefore, in patients with acute hearing loss and vertigo without obvious neurologic deficits, cerebellar infarction should be considered even if the patient is at low risk, as this can be the first sign of a life-threatening basilar artery thrombosis.

一名57歲男性經前庭功能檢查及磁振造影檢查診斷為左側小腦梗塞。初期表現症狀為單側突發性聽力障礙及持續性眩暈症。腦部磁振造影檢查顯示為前下小腦動脈及後下小腦動脈急性梗塞。因此，在沒有明顯的神經學症狀下，病患有突發性聽力障礙及眩暈症時應將小腦梗塞納入考量，因為這有可能是基底動脈狹窄的初期症狀。
