Abstract
BACKGROUND
Double origin of the posterior inferior cerebellar artery (DOPICA) is a rare cranial imaging finding with an incidence of 0.36-6% reported in various retrospective studies. Aneurysms on a DOPICA are even rarer.
CASE DESCRIPTION
A 34-year-old women hospitalised for subarachnoid haemorrhage showed a ruptured aneurysm arising from the caudal channel of the DOPICA. Endovascular treatment was selected, and the aneurysm was successfully and completely embolised using two coils.
CONCLUSIONS
To date, a total of three previous saccular aneurysms of the DOPICA itself have been reported, all of which were treated using endovascular methods. Our case is the first report of a ruptured saccular aneurysm arising from the non-branching segment of the caudal channel of the DOPICA.
摘要
背景
小脑后下动脉双重起源（DOPICA）是一种罕见的颅影像表现，在各种回顾性研究中的发生率为 0.36-6%。DOPICA 上的动脉瘤更为罕见。
病例描述
一名 34 岁女性因蛛网膜下腔出血住院，显示出起源于 DOPICA 尾侧通道的破裂性动脉瘤。选择了血管内治疗，使用两个线圈成功且完全栓塞了动脉瘤。
结论
迄今为止，总共报告了三个 DOPICA 本身的囊状动脉瘤，均采用血管内方法治疗。我们的病例是首例报道起源于 DOPICA 尾侧通道非分支段的破裂性囊状动脉瘤。
