OBJECTIVE
We report a case of a ruptured cerebral aneurysm in which a bifurcation pattern at the tip of the basilar artery was asymmetric fusion type and the superior cerebellar artery (SCA) branched from the posterior cerebral artery (PCA) on the caudal fusion type side.
CASE PRESENTATION
A 45-year-old woman presented with a subarachnoid hemorrhage with a headache. Cerebral angiography revealed that the right SCA diverged from the PCA and a small cerebral aneurysm had developed at this site. This cerebral aneurysm was successfully treated by coil embolization.
CONCLUSION
There have been no previous reports on cerebral aneurysms at the site of this normal variation.
目的
我们报告一例破裂性脑动脉瘤病例，其中基底动脉顶端的分叉模式为不对称融合型，且小脑上动脉（SCA）在尾侧融合型一侧从大脑后动脉（PCA）分支。
病例介绍
一名45岁女性因头痛伴蛛网膜下腔出血就诊。脑血管造影显示右侧SCA从PCA分出，且在此部位形成了一个小的脑动脉瘤。该脑动脉瘤通过弹簧圈栓塞成功治疗。
结论
此前尚无关于这种正常变异部位脑动脉瘤的报道。
