A 74-year-old woman, with hypertension and dilated cardiomyopathy, presented with sudden onset of diplopia without vertigo and other neurological symptom. Examination revealed left inferior rectus muscle paresis. Other neurological findings were normal. She had no cerebellar ataxia and sensori-motor dysfunction. Magnetic resonance imaging showed increased signal intensity on T2-weighted and proton density-weighted images in the right ventral midbrain, compatible with infarction involving the fascicular oculomotor fibers. Complete resolution of the diplopia and normal ocular motility were noted 3 months after the onset of the diplopia. Focal ischemic midbrain lesions should be considered in cases of isolated partial oculomotor nerve paresis.
一名74岁女性，患有高血压和扩张型心肌病，突发复视，无眩晕及其他神经症状。检查发现左侧下直肌麻痹。其他神经检查结果正常。她没有小脑共济失调和感觉运动功能障碍。磁共振成像显示右侧腹侧中脑在T2加权像和质子密度加权像上信号强度增加，符合动眼神经束状纤维梗死。复视发作3个月后，复视完全消失，眼球运动恢复正常。孤立性部分动眼神经麻痹病例应考虑局灶性缺血性中脑病变。
