[A case of popliteal pseudoaneurysm caused by femoral exostoses]

A popliteal artery pseudo aneurysm secondary to compression by a bony exostosis is recorded to call attention to this unusual etiological mechanism in a 32 years old woman. Restoration of arterial continuity was achieved by resection of the pseudo aneurysm and end to end anastomosis of the artery. A review of the literature discloses 32 cases of popliteal aneurysms associated to bony exostosis.
