摘 要:目的 探讨单纯外伤性蛛网膜下腔出血(STSAH)的CT表现特征及其诊断价值. 方法 对124例STSAH患者的CT表现进行回顾性分析,其中102例经CT复查及治疗结果证实. 结果 STSAH的出血部位分布于:大脑纵裂池56例(45.2%);脑干周围池37例(29.8%);大脑侧裂池22例(17.7%);脑表面沟9例(7.3%).其主要CT表现特征为:①纵裂池染色半球面边缘毛糙征;②脑干周围池积血征;③侧裂池或脑表面沟铸型染色征. 结论 ①CT据上述特征性表现可作出STSAH诊断;②大脑纵裂池出血时的冠状位重建图像能为鉴别诊断提供更多有价值的信息;③CT复查有助于验证诊断和及时检出迟发性脑出血.
