Abstract
BACKGROUND
The authors report an unusual case of the radiological appearance of diffuse subarachnoid hemorrhage on brain computed tomographic (CT) scan in a patient with post-resuscitation anoxic encephalopathy.
CLINICAL PRESENTATION
A young man with chronic renal failure collapsed unconscious while starting hemodialysis and was revived after resuscitation for almost one hour. He was shifted to intensive care unit and subsequent CT scan after 3 days showed a picture compatible with diffuse subarachnoid hemorrhage. The subsequent lumbar puncture showed no evidence of subarchnoid hemorrhage while the attenuation at the basal cistern on CT brain was consistent with pseudosubarachnoid hemorrhage. A four vessel angiography done subsequently confirmed anoxic encephalopathy.
CONCLUSION
Anoxic encephalopathy can mimic diffuse subarachnoid hemorrhage on CT.
摘要
背景
作者报告了一例复苏后缺氧性脑病患者脑部计算机断层扫描（CT）显示弥漫性蛛网膜下腔出血的罕见影像学表现病例。
临床表现
一名患有慢性肾衰竭的年轻男子在开始血液透析时昏迷倒地，复苏近一小时后苏醒。他被转移到重症监护病房，3天后的后续CT扫描显示出与弥漫性蛛网膜下腔出血相符的影像。随后的腰椎穿刺未发现蛛网膜下腔出血的证据，而脑部CT上基底池的衰减与假性蛛网膜下腔出血一致。随后进行的四血管血管造影证实为缺氧性脑病。
结论
缺氧性脑病在CT上可模拟弥漫性蛛网膜下腔出血。
