A 36-year-old male presented with an extremely rare dissecting aneurysm of the posterior communicating artery manifesting as severe occipital headache. Magnetic resonance (MR) imaging revealed a partially thrombosed aneurysm of the right posterior communicating artery and angiography showed the pearl and string sign. Three months later, repeat angiography showed that the aneurysm was completely thrombosed and the posterior communicating artery was occluded. Magnetic resonance (MR) imaging showed an intimal flap. These neuroradiological findings demonstrated that the aneurysm was a dissecting aneurysm of the right posterior communicating artery. He was discharged with no neurological deficit.
一名36岁男性因极其罕见的后交通动脉夹层动脉瘤就诊，表现为严重的枕部头痛。磁共振成像显示右侧后交通动脉有部分血栓形成的动脉瘤，血管造影显示珍珠串征。三个月后，重复血管造影显示动脉瘤完全血栓形成，后交通动脉闭塞。磁共振成像显示有内膜瓣。这些神经放射学表现表明该动脉瘤为右侧后交通动脉夹层动脉瘤。他出院时无神经功能缺损。
