Posterior cerebral artery (PCA) aneurysms are rare and usually arise from proximal portion of the artery. The distal location is even less frequent, and aneurysms in this location tend to be larger and dissecting. Although they can be treated by direct surgery, recently endovascular procedures have been preferred in some centers. We report a case of large aneurysm of the posterior cerebral artery in a 45-year-old female presenting with headache. An uneventful endovascular treatment was performed with stent and platinum coils achieving total occlusion of the aneurysm, and the patient had good recovery. The findings are compared to earlier reports and literature regarding the issue is discussed.

大脑后动脉 (PCA) 动脉瘤很少见，通常起源于动脉的近端。远端位置更不常见，并且该位置的动脉瘤往往较大且夹层。虽然它们可以通过直接手术治疗，但最近一些中心首选血管内手术。我们报告了一例出现头痛的 45 岁女性大脑后动脉大动脉瘤。使用支架和铂线圈进行了平稳的血管内治疗，实现了动脉瘤的完全闭塞，患者恢复良好。将这些发现与早期的报告进行了比较，并讨论了有关该问题的文献。
