A 27 year old woman with mitral valve prolapse presented with somnolence, bilateral Babinski signs, and grasp reflexes. As somnolence cleared, vertical gaze palsy and Korsakoffian memory deficit were apparent. Initial CT scan was normal, but NMR scan 24 hours after the onset of symptoms revealed prolonged T2 relaxation in medial thalami bilaterally, facilitating diagnosis of bithalamic infarction. Subsequent CT scans delineated infarction in the vascular territory of the paramedian thalamic arteries. Previous clinical reports and the neuro- and vascular anatomy underlying this syndrome are reviewed, including cases that suggest a relationship to the syndrome of transient global amnesia.
一名患有二尖瓣脱垂的27岁女性出现嗜睡、双侧巴宾斯基征和抓握反射。随着嗜睡症状消退，垂直凝视麻痹和柯萨科夫遗忘症明显。最初的CT扫描结果正常，但症状发作24小时后的核磁共振扫描显示双侧丘脑内侧T2弛豫时间延长，有助于诊断双侧丘脑梗死。随后的CT扫描确定了丘脑旁正中动脉血管区域的梗死。本文回顾了以往的临床报告以及该综合征的神经和血管解剖结构，包括一些提示与短暂性全面性遗忘症综合征有关的病例。
