Abstract
Fibromuscular dysplasia (FMD) is an arterial disease characterized by fibrous arterial wall thickening and irregular proliferation and degeneration of smooth muscle cells in muscular arteries. Abdominal aortic aneurysms (AAA) are rare, with only a few reported cases. A characteristic feature of AAA is an aneurysm protruding forward near the terminal aorta with stenosis. Here, we report a rare case of a 66-year-old woman who underwent abdominal aortic replacement for a fusiform AAA, diagnosed with aortic FMD (without stenotic lesions) on pathological examination.
