We herein report a case of fenestration of the superior cerebellar artery (SCA), which was incidentally diagnosed by magnetic resonance (MR) angiography. A 65-year-old woman was referred to our hospital for unruptured cerebral aneurysms. MR angiography revealed 2 unruptured aneurysms. It also showed fenestration of the left SCA near its origin from the basilar artery, as well as several other vascular variations: a left common carotid artery arising from the brachiocephalic trunk, and a right vertebral artery terminating to the right posterior inferior cerebellar artery. Yearly observation was chosen as a treatment strategy due to the small size of the cerebral aneurysms. According to previous reports, SCA fenestration is an extremely rare variation. This is the second case of SCA fenestration diagnosed by MR angiography in the relevant English-language literature.
我们在此报告一例小脑上动脉（SCA）开窗畸形，该病例由磁共振（MR）血管造影偶然诊断。一名65岁女性因未破裂脑动脉瘤转诊至我院。MR血管造影显示2个未破裂动脉瘤。还显示左SCA在其从基底动脉发出处附近存在开窗畸形，以及其他几种血管变异：左颈总动脉起自头臂干，右椎动脉终止于右小脑后下动脉。由于脑动脉瘤体积较小，选择每年观察作为治疗策略。根据既往报道，SCA开窗畸形是一种极其罕见的变异。这是相关英文文献中第二例通过MR血管造影诊断的SCA开窗畸形病例。
