We describe an unusual presentation of a ruptured aneurysm of the posterior communicating artery with an acute subdural hematoma (SDH) located in the posterior fossa. We also reviewed the literature, focusing on the location of this intracranial hematoma.
An 83-year-old woman was admitted to our institution with recent sudden headache and dizziness. Magnetic resonance imaging showed a thin collection of blood in the subdural space adjacent to the clivus, along the wall of the posterior fossa, and at the cervical spine level. A right posterior communicating artery aneurysm was diagnosed using computed tomography angiography and digital subtraction angiography. The aneurysm had two lobes, one of which was attached to the right dorsum sellae. The aneurysm was occluded by stent-assisted coil embolization. The patient was discharged 3 weeks after admission with absence of neurological deficit.
A ruptured aneurysm of the posterior communicating artery may cause an acute SDH.
我们描述了一例后交通动脉动脉瘤破裂并伴有位于后颅窝的急性硬膜下血肿（SDH）的不寻常表现。我们还回顾了文献，重点关注这种颅内血肿的位置。
一名83岁女性因近期突发头痛和头晕入住我院。磁共振成像显示在斜坡旁、后颅窝壁及颈椎水平的硬膜下间隙有少量血液积聚。通过计算机断层血管造影和数字减影血管造影诊断为右侧后交通动脉瘤。该动脉瘤有两个叶，其中一个附着于右侧鞍背。通过支架辅助弹簧圈栓塞术闭塞了动脉瘤。患者入院3周后出院，无神经功能缺损。
后交通动脉动脉瘤破裂可能导致急性硬膜下血肿。
