title: [Rupture of a popliteal artery pseudo-aneurysm revealing a tibial osteochondroma: case report and review of the literature].
abstract: Osteochondroma constitutes the most frequent bone tumor. It is exceptionally responsible for vascular complications from which pseudo-aneurysms constitute the most frequent entity. We report the case of a 20-year-old patient who presented with acute pain of the left knee following a sports' accident. Vascular ultrasonography showed the rupture of a false aneurysm of the popliteal artery. An arteriography confirmed the diagnosis by showing contrast leakage at the level of the below-knee popliteal artery projecting over an osteochondroma. Surgery was undertaken to close the aneurysm an insert a venous graft. The procedure was completed by excision of the bone tumor. Vascular complications of osteochondroma are rare but should be considered in young patients with a false aneurysm of the popliteal artery. Surgery is required for the treatment of false aneurysms on exostosis.
