Cerebral artery fenestrations are rare anatomical variants usually detected incidentally on cross-sectional imaging or cerebral angiography. Although considered benign findings, many reports have described their association with vascular abnormalities such as aneurysms or arteriovenous malformations, and to a lesser extent with ischemic or hemorrhagic complications. We report a case of middle cerebral artery fenestration associated with subarachnoid hemorrhage and middle cerebral artery thrombosis. To our knowledge, there has been no prior report of middle cerebral artery fenestration with a similar presentation.
大脑动脉开窗是一种罕见的解剖变异，通常在横断面成像或脑血管造影时偶然发现。尽管被认为是良性表现，但许多报告描述了它们与血管异常（如动脉瘤或动静脉畸形）的关联，在较小程度上也与缺血性或出血性并发症有关。我们报告一例大脑中动脉开窗合并蛛网膜下腔出血和大脑中动脉血栓形成的病例。据我们所知，此前尚无类似表现的大脑中动脉开窗的报告。
