Fibromuscular dysplasia (FMD) mainly develops in medium-sized arteries, including renal, extracranial, and extremity arteries, but it rarely causes abdominal aortic aneurysm (AAA). A 69-year-old woman with AAA diagnosed on ultrasonography by a home doctor visited our hospital. Contrast-enhanced computed tomography revealed a saccular aneurysm of terminal abdominal aorta. We performed abdominal aortic replacement and resected the section with aneurysm. Pathological examination of the wall tissue of the resected aneurysm revealed findings that are consistent with FMD. We report this case of AAA caused by aortic FMD because of its rarity.

纤维肌发育不良（FMD）主要发生于中等大小动脉，包括肾动脉、颅外动脉和四肢动脉，但很少引起腹主动脉瘤（AAA）。一名69岁女性经家庭医生超声检查诊断为腹主动脉瘤，前来我院就诊。增强计算机断层扫描显示腹主动脉末端囊状动脉瘤。我们进行了腹主动脉置换术，并切除了动脉瘤部分。对切除的动脉瘤壁组织进行病理检查，结果与纤维肌发育不良相符。由于这种情况罕见，我们报告了这例由主动脉纤维肌发育不良引起的腹主动脉瘤病例。
