Cerebral infarction in the setting of vasospasm due to subarachnoid hemorrhage (SAH) is a known complication of aneurysmal rupture. Computed tomography (CT) has been instrumental in making this diagnosis; however, focal hypodense lesions on CT scan do not always represent infarcted tissue. Two patients are presented here who had CT hypodense lesions in regions of cerebral vasospasm following subarachnoid hemorrhage.
蛛网膜下腔出血（SAH）所致血管痉挛情况下的脑梗死是动脉瘤破裂的一种已知并发症。计算机断层扫描（CT）在做出这一诊断中发挥了重要作用；然而，CT扫描上的局灶性低密度病变并不总是代表梗死组织。本文介绍了两名蛛网膜下腔出血后脑血管痉挛区域出现CT低密度病变的患者。
