A patient had a subarachnoid hemorrhage in 1969. Four-vessel angiography demonstrated an infundibular widening of the posterior communicating artery alone. In 1978, nine years later, angiography demonstrated that the infundibular widening had enlarged and developed into an aneurysm, though unruptured. Another aneurysm of the anterior communicating artery was also found. Both were confirmed at operation and clipped. Review of the pertinent literature emphasizes that the infundibular widening may be preaneurysmal.
一名患者于1969年发生蛛网膜下腔出血。四血管造影显示仅后交通动脉漏斗部增宽。九年后的1978年，血管造影显示漏斗部增宽扩大并发展为动脉瘤，虽未破裂。还发现了前交通动脉的另一个动脉瘤。两者均在手术中得到证实并夹闭。相关文献回顾强调漏斗部增宽可能是动脉瘤形成前的表现。
