BACKGROUND
Isolated superior rectus palsy due to a contralateral midbrain lesion has not been reported.
CASE DESCRIPTION
A 71-year-old woman suddenly developed diplopia. Examination showed that she had isolated superior rectus paresis. Magnetic resonance imaging showed a tiny infarct at the area of the oculomotor nucleus on the contralateral side.
CONCLUSION
Isolated superior rectus palsy may be caused by a contralateral midbrain lesion that selectively involves crossing superior rectus nerve fibers.
背景
由对侧中脑病变引起的孤立性上直肌麻痹尚未见报道。
病例描述
一名71岁女性突然出现复视。检查显示她患有孤立性上直肌麻痹。磁共振成像显示对侧动眼神经核区域有一个微小梗死灶。
结论
孤立性上直肌麻痹可能由选择性累及交叉的上直肌神经纤维的对侧中脑病变引起。
