Cystic arterial adventitial degeneration.
Cystic degeneration of the adventitia is a rare entity occurring most commonly in the popliteal artery: only a few cases involving the external iliac, femoral, radial, and ulnar arteries have been reported. The authors describe 2 cases, one of which appears to be the first report of the disease in the external iliac artery in a child.
