We report a case of a ruptured isolated true external iliac artery aneurysm (EIAA). A 78-year-old woman was admitted to our institution in a shock state after the sudden onset of severe pain in the right hypogastric region. A pulsating mass was found in her right lower abdomen. Computed tomography (CT) with contrast medium showed an isolated EIAA, 40 mm in diameter, with a massive retroperitoneal hematoma. She underwent emergency resection of the aneurysm and reconstruction of the affected artery, without any complications. Histological examination confirmed a true aneurysm caused by cystic medial necrosis (CMN). She had no ocular, cardiac, or orthopedic abnormalities. We review the literature on isolated true aneurysms of the external iliac artery, which are extremely rare, and discuss their clinical manifestations.
我们报告一例孤立性真性髂外动脉瘤（EIAA）破裂的病例。一名78岁女性因右下腹突然出现剧痛后以休克状态入住我院。在她的右下腹发现一个搏动性肿块。增强计算机断层扫描（CT）显示一个直径40毫米的孤立性EIAA，伴有大量腹膜后血肿。她接受了动脉瘤急诊切除术和患侧动脉重建术，未出现任何并发症。组织学检查证实为囊性中膜坏死（CMN）所致的真性动脉瘤。她没有眼部、心脏或骨科异常。我们回顾了关于极其罕见的孤立性真性髂外动脉瘤的文献，并讨论了它们的临床表现。
