Traumatic pseudoaneurysm in a wrestler.

An 18-year-old man sought treatment for a pulsatile mass in the medial distal thigh four years after he had sustained blunt trauma during a wrestling match. Investigation, which included magnetic resonance imaging and arteriography, showed the mass to be a pseudoaneurysm, which should be considered in the differential diagnosis of masses resulting from direct, blunt trauma. At exploration, a pseudoaneurysmic thrombus in the superficial femoral artery was evacuated and the vessel was repaired with an interposition graft of reversed saphenous vein, followed by complete recovery of the patient.
