摘　　要：脑凸面蛛网膜下腔出血(cSAH)是非外伤性蛛网膜下腔出血的一种少见类型,临床上可表现为短暂性、发作性、刻板性的神经系统症状,有时误诊为短暂性脑缺血发作。作者报道了3例以发作性症状为表现的cSAH,1例为烟雾病,1例为颅内大动脉狭窄,1例为疑似脑淀粉样血管病并结合文献分析其临床特征及发病机制。因此,临床上对于表现为cSAH的患者,需考虑多方面的病因,完善必要相关检查,以尽早诊断、早干预,改善患者预后。Convexal subarachnoid hemorrhage(cSAH)is a rare type of non-traumatic subarachnoid hemorrhage.It can be clinically characterized by transient,paroxysmal and stereotypical neurological symptoms,and misdiagnosed as transient ischemic attack sometime.Three cases of cSAH with paroxysmal symptoms were reported.One case was Moyamoya disease,one was intracranial artery stenosis,and the remaining one was possible cerebral amyloid angiopathy The clinical features and pathogenesis of cSAH were analyzed.Thus,it is necessary to consider various etiology and complete necessary relevant examinations for cases with cSAH in clinical practice,so as to diagnose and intervene it as early as possible to improve the prognosis of patients.
