Abstract
A 19-year-old man presented to our institution with a 4-month history of a pulsatile mass in the left popliteal fossa. Evaluation including plain x-ray films, MRI, and arteriography revealed a pseudoaneurysm associated with an underlying exostosis of the distal femur. The pseudoaneurysm was repaired with a saphenous vein patch and the exostosis was excised. This case is reported in conjunction with an extensive review of the literature, which yielded only 25 similar cases reported in the English language since 1953. The majority of cases involved young men (20/26), whose ages ranged from 9 to 45 years (mean 20 years). Fifteen of the 26 cases involved isolated exostoses, and in less than half (12/26), antecedent trauma was identified as a cause of the pseudoaneurysm. The origin of exostoses and their relationship to popliteal pseudoaneurysms are discussed. Repair of the pseudoaneurysm and excision of the involved exostosis are recommended.
