We report two patients with posterior fossa neoplasms who demonstrated asymmetrically impaired horizontal ocular pursuit documented with electrooculography. One patient had impaired pursuit contralateral to a pontomedullary lesion, whereas the second patient had impaired pursuit ipsilateral to a pontocerebellar lesion. These patients demonstrate that posterior fossa lesions may impair ocular pursuit either contralaterally or ipsilaterally unlike cerebral hemispheric lesions, which impair ocular pursuit ipsilaterally or bilaterally.
我们报告了两名患有后颅窝肿瘤的患者,通过眼电图记录显示其水平眼球追踪不对称受损。一名患者在脑桥延髓病变对侧的追踪受损,而另一名患者在脑桥小脑病变同侧的追踪受损。这些患者表明,与大脑半球病变不同,后颅窝病变可能导致眼球追踪对侧或同侧受损,大脑半球病变导致眼球追踪同侧或双侧受损。
