A 52-year-old man was referred to our institution because of a solitary aneurysm of the left common iliac artery. The presence of the aneurysm was demonstrated by CT and angiography. The aneurysm had a diameter of about 30mm. The walls of the bilateral external iliac arteries were irregular, like a string of beads. The aneurysm was resected and replaced with a vascular prosthesis. Histological examination of the aneurysm and a part of the left external iliac artery indicated a diagnosis compatible with fibromuscular dysplasia (FMD: medial fibroplasia). A solitary iliac aneurysm is rare, and is usually due to atherosclerosis. However, the aneurysm in this case was related to FMD. To the best of our knowledge, only one other case of a solitary common iliac aneurysm caused by FMD has so far been described.
