Abstract

A 40-year-old male smoker presented with a ruptured saccular aneurysm that formed de novo 10 months after normal magnetic resonance (MR) angiography findings. Computed tomography of the head at the second admission showed subarachnoid hemorrhage in the interhemispheric fissure and anterior basal cistern. MR and conventional cerebral angiography revealed an aneurysm arising from the anterior communicating artery (AcomA). MR angiography performed 10 months earlier, when he experienced transient loss of consciousness, revealed no anomalies at the AcomA. Intraoperatively, the de novo aneurysm was found to be a typical saccular aneurysm with a fragile wall.

摘要

一名40岁男性吸烟者,在磁共振(MR)血管造影结果正常10个月后出现了一个新形成的囊状动脉瘤破裂。第二次入院时的头部计算机断层扫描显示大脑半球间裂和前基底池蛛网膜下腔出血。MR和传统脑血管造影显示一个起自前交通动脉(AcomA)的动脉瘤。10个月前他出现短暂意识丧失时进行的MR血管造影显示AcomA没有异常。术中发现这个新形成的动脉瘤是一个典型的囊状动脉瘤,壁很薄。
