The case is presented of a 23-year-old man suffering ischemic brain infarction from spontaneous thrombosis of a left posterior cerebral artery P1-P2 junction aneurysm. Vasospasm and/or partial parent vessel occlusion were documented by magnetic resonance (MR) imaging and angiography. Repeat cerebral angiography and MR imaging 3 months later revealed patency of the posterior cerebral artery and luminal filling of a 1-cm fusiform aneurysm, which was successfully trapped at surgery.
本文报告了一名23岁男性患者，因左大脑后动脉P1-P2交界处动脉瘤自发血栓形成导致缺血性脑梗死。磁共振成像（MR）和血管造影证实存在血管痉挛和/或部分供血血管闭塞。3个月后复查脑血管造影和MR成像显示大脑后动脉通畅，有一个1厘米的梭形动脉瘤腔内充盈，该动脉瘤在手术中成功被夹闭。
