Artery of Percheron (AOP) occlusion is a rare cause of ischemic stroke characterized by bilateral paramedian thalamic infarcts, with or without mesencephalic infarction. Clinically it presents with mental state disturbances, hypersomnolence, aphasia/dysarthria, amnesia and ocular movement disorders, including vertical gaze palsy. Here, we report a case of cardioembolic AOP infarction in a 37-year-old woman with rheumatic mitral valvular stenosis. This case is being reported to highlight the interesting clinical and neuroimaging features of this rare condition, and the differential diagnosis of AOP infarction on imaging have been discussed.
Percheron动脉(AOP)闭塞是缺血性卒中的罕见病因,其特征为双侧丘脑旁正中梗死,可伴有或不伴有中脑梗死。临床上表现为精神状态紊乱、嗜睡、失语/构音障碍、失忆以及眼球运动障碍,包括垂直凝视麻痹。在此,我们报告一例患有风湿性二尖瓣狭窄的37岁女性发生心源性栓塞性AOP梗死的病例。报告该病例是为了突出这种罕见疾病有趣的临床和神经影像学特征,并讨论了AOP梗死在影像学上的鉴别诊断。
