BACKGROUND
Nontraumatic convexal subarachnoid hemorrhage (cSAH) is a rare type of atypical subarachnoid hemorrhage. It mainly presents as a focal and transient neurological deficit with similar manifestations as transient ischemic attack.
CASE SUMMARY
We report a case of a 64-year-old man who visited the hospital with paroxysmal left-sided numbness and weakness is presented in this study. Computed tomography examination indicated a high-density image of the right frontal-parietal sulcus. Digital subtraction angiography showed severe stenosis at the right anterior cerebral artery A2-A3 junction (stenosis rate approximately 70%).
CONCLUSION
The findings of this case indicate that anterior cerebral artery stenosis may lead to the occurrence of cSAH.
背景
非创伤性凸面蛛网膜下腔出血（cSAH）是一种罕见的非典型蛛网膜下腔出血类型。它主要表现为局灶性和短暂性神经功能缺损，临床表现与短暂性脑缺血发作相似。
病例摘要
本研究报告了一例64岁男性患者，该患者因阵发性左侧麻木和无力前来就诊。计算机断层扫描检查显示右侧额顶沟有高密度影像。数字减影血管造影显示右侧大脑前动脉A2-A3交界处严重狭窄（狭窄率约70%）。
结论
该病例结果表明大脑前动脉狭窄可能导致cSAH的发生。
