Two patients who presented with abnormal neurological findings and focal abnormalities on static brain imaging, were felt to have infarction in the distribution of the posterior cerebral artery. However, the posterior flow study delineated the cause of the abnormality as being a fenestrated anomaly of the sagittal sinus. The incidence of occlusive disease of the posterior cerebral artery, its clinical and scintigraphic presentation and the potential pitfalls for misinterpretation are reviewed.
两名患者出现神经系统异常表现及静态脑成像的局灶性异常，最初认为是大脑后动脉供血区域梗死。然而，进一步的血流研究明确异常原因是矢状窦开窗畸形。本文回顾了大脑后动脉闭塞性疾病的发病率、临床及闪烁显像表现，以及可能导致误诊的潜在陷阱。
