We report three cases of small cerebellar infarcts mimicking labyrinthine dysfunction. A sudden rotatory vertigo might be the only presenting symptom of a cerebellar infarct. In these cases, the clinical features may closely mimick an acute peripheral labyrinthine disorder. However, the absence of nystagmus or a direction changing nystagmus with different eye position and the normality of caloric responses may be suggestive of a cerebellar infarct. This syndrome may be explained by the involvement of the nodulus, part of the flocculo-nodular complex, that has primary vestibular connections. Cerebellar infarcts mimicking labyrinthine dysfunctions involved usually the cerebellar territory of the posterior inferior cerebellar artery (PICA). Infarcts may be limited to the territory of the medial branch of the PICA which supplies the nodulus.
我们报告了三例酷似迷路功能障碍的小脑血管性梗死病例。突发旋转性眩晕可能是小脑血管性梗死的唯一症状。在这些病例中，临床特征可能与急性外周迷路疾病极为相似。然而，无眼球震颤或眼球位置不同时方向改变的眼球震颤以及冷热试验反应正常可能提示小脑血管性梗死。该综合征可通过绒球小结复合体的一部分小结受累来解释，小结具有主要的前庭连接。酷似迷路功能障碍的小脑血管性梗死通常累及小脑后下动脉（PICA）的小脑区域。梗死可能局限于供应小结的PICA内侧支的区域。
