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.
