Spontaneous femoral artery pseudoaneurysm in a young patient.

Spontaneous femoral artery pseudoaneurysm is a rare disease and reported cases are very rare. Most of them are related to an underlying pathology of either atherosclerotic disease or connective tissue disease. We present a healthy, 29-year-old man with 2-month history of a painful pulsating mass at the level of the lower right thigh with no previous history of trauma, surgery, or puncture of the femoral artery. An angiogram revealed a right superficial femoral artery pseudoaneurysm. It was treated surgically by resection of the aneurysm and reconstruction with an interpositional saphenous vein graft. We report this case because of the rarity of this condition in a young patient with no underlying pathology.
