Based on the complexity of functional anatomy, a small infarction in the medulla can produce various types of clinical symptoms or signs depending on the location of this infarction. We describe the case of a 46-year-old man who presented with sudden onset of body lateropulsion to the left side and numbness of the ipsilateral fingers. 3-tesla diffusion-weighted magnetic resonance imaging with a section thickness of 2 mm revealed a small infarction in the dorsal part of the left middle medulla. To our knowledge, this is the first case report describing vestibular dysfunction apparent upon otoelectrophysiological examination but without vestibular symptoms or signs except for body lateropulsion.
基于功能解剖的复杂性，延髓的小梗死灶可根据梗死部位产生各种类型的临床症状或体征。我们描述了一名46岁男性的病例，该患者突然出现身体向左偏斜和同侧手指麻木。采用层厚2mm的3T扩散加权磁共振成像显示左中延髓背侧有一个小梗死灶。据我们所知，这是首例报告，描述了经耳电生理检查发现明显的前庭功能障碍，但除身体偏斜外无前庭症状或体征。
