Fibrodysplastic Popliteal Aneurysm and Dilatation of Pedal Artery

We report a case of an asymptomatic popliteal aneurysm due to fibromuscular dysplasia (FMD), associated with suspected FMD of pedal artery on a 63-year-old woman. The popliteal aneurysm was resected. An in situ interposition of a short segment of hypogastric artery was performed to restore the arterial continuity. Popliteal FMD was confirmed by histological findings. Only 5 cases are reported in literature. FMD of pedal artery was suspected on the CT-scan aspect. FMD is a rare cause of popliteal aneurysm. To our knowledge, this is the first report of suspected fibrodysplastic dilatation of a foot artery.
