Abstract

We herein report a patient who developed transient prosopometamorphopsia restricted to the left eye caused by ischemia of the right splenium of the corpus callosum. A 66-year-old right-handed woman suddenly noticed that the left eyes of people she encountered appeared markedly adducted to their noses. On emergent admission, neurological and ophthalmological examinations revealed no abnormalities. Diffusion-weighted magnetic resonance imaging showed a small, hyperintense lesion at the right splenium of the corpus callosum. In this case, information on the right visual field projected to the left occipital lobe might have been obstructed on transmission to the right hemisphere through the splenium of the corpus callosum.

摘要

我们在此报告一名患者，其因胼胝体压部右侧缺血而出现仅累及左眼的短暂性人面变形视幻觉。一名66岁右利手女性突然注意到，她遇到的人的左眼明显内收至鼻子处。急诊入院时，神经科和眼科检查均未发现异常。弥散加权磁共振成像显示胼胝体压部右侧有一个小的高信号病变。在这种情况下，投射到左枕叶的右侧视野信息在通过胼胝体压部传输到右半球时可能受到了阻碍。
