BACKGROUND Multiple aneurysms, associated with distal anterior cerebral artery (ACA) aneurysm, are not rare; therefore, it is important to examine multiplicity of the aneurysms preoperatively. CASE REPORT A case of ruptured distal ACA aneurysm, associated with another one in a mirror position, is reported. A 43-year-old woman suffered subarachnoid hemorrhage. Conventional angiography demonstrated a saccular aneurysm on the bifurcation of the right or left distal ACA; however, magnetic resonance angiography (MRA) revealed two mirror-image aneurysms on both bifurcations. CONCLUSION MRA was useful for preoperative diagnosis of kissing aneurysms on distal ACAs.
背景
与大脑前动脉（ACA）远端动脉瘤相关的多发性动脉瘤并不罕见；因此，术前检查动脉瘤的多发性很重要。病例报告：报告一例破裂的ACA远端动脉瘤病例，其在镜像位置还有另一处动脉瘤。一名43岁女性发生蛛网膜下腔出血。传统血管造影显示右侧或左侧ACA远端分叉处有一个囊状动脉瘤；然而，磁共振血管造影（MRA）显示两侧分叉处有两个镜像动脉瘤。结论：MRA有助于术前诊断ACA远端的对吻动脉瘤。
