A 72-year-old hypertensive woman developed acute diplopia and right upper lid ptosis. Examination showed a partial right third nerve palsy with complete ptosis, moderately impaired adduction and supraduction, and sparing of infraduction and the pupil. There were no other neurologic deficits. Brain MRI with diffusion weighting demonstrated an infarct in the right paramedian midbrain tegmentum along the course of the third nerve fascicles. The clinical deficit and neuroimaging in this case provide further support for a previously suggested topographic organization of the fascicles of the third nerve within the brainstem.
一位 72 岁的高血压女性出现急性复视和右上眼睑下垂。检查发现右侧动眼神经部分麻痹，伴有完全上睑下垂、眼球内收和上转中度受损，下转和瞳孔不受影响。无其他神经功能缺损。弥散加权脑 MRI 显示右侧中脑被盖旁正中沿第三神经纤维束的梗死。本例的临床缺损和神经影像学结果进一步支持了先前提出的第三神经纤维束在脑干内的解剖定位组织。
