A 67-year-old man with hypertension and type 2 diabetes mellitus was admitted to our hospital because of left hearing loss and vertical diplopia. A neurological examination showed ocular torsion, skew deviation, and sensorineural hearing loss in the left ear. Brainstem and cerebellar neurological signs were not observed. Left middle cerebellar peduncle infarction was evident on magnetic resonance imaging. He was treated with antiplatelet, however, the infarct progressed after this administration. Ocular tilt reaction (OTR) involves the triad of ocular torsion, skew deviation, and head tilt. Ipsiversive OTR components associated with hearing loss can be early diagnostic signs of anterior inferior cerebellar artery infarction.
一名患有高血压和2型糖尿病的67岁男性因左耳听力丧失和垂直复视而入住我院。神经系统检查显示眼球扭转、斜向偏斜和左耳感音神经性听力丧失。未观察到脑干和小脑神经系统体征。磁共振成像显示左小脑中间脚梗死明显。他接受了抗血小板治疗，然而，给药后梗死仍有进展。眼倾斜反应（OTR）包括眼球扭转、斜向偏斜和头部倾斜三联征。与听力丧失相关的同侧性OTR成分可能是小脑前下动脉梗死的早期诊断体征。
