BACKGROUND
Stroke of the corpus callosum is uncommon, known to be associated with disturbance of higher brain function including hemifacial metamorphosia, but has never been reported to cause visual hallucinations.
METHODS
We report on a case of a 71-year-old woman who presented to the emergency department with a 3-day history of intermittent, formed visual hallucinations in the left visual field, often triggered by eye closure or darkness.
RESULTS
Neurologic examination was normal including cognition and affect, visual acuity, and visual fields. Electroencephalogram was normal. Magnetic resonance imaging scan of her brain showed a small stroke in the right inferior forceps major. Hallucinations resolved on day 2 of her admission, and she remains well more than a year later.
CONCLUSIONS
This is the first report of transient visual hallucinations after a callosal stroke, which is an uncommon territory of stroke and a rare presentation of stroke.
背景
胼胝体中风并不常见，已知与包括半侧面部变形在内的高级脑功能障碍有关，但从未有过导致视幻觉的报道。
方法
我们报告了一例71岁女性病例，该患者因左侧视野间歇性、成形视幻觉3天的病史就诊于急诊科，这些幻觉常由闭眼或黑暗引发。
结果
神经系统检查正常，包括认知和情感、视力及视野。脑电图正常。她的脑部磁共振成像扫描显示右侧下纵束有一个小中风灶。入院第2天时幻觉消失，一年多后她情况良好。
结论
这是胼胝体中风后出现短暂视幻觉的首例报告，胼胝体是一个不常见的中风部位，中风表现也很罕见。
