Osteochondromas or bone exostoses are bone tumors commonly found in adolescents or young adults. These benign tumors are usually incidentally discovered, exceptionally by a vascular or nervous complication. We report the case of a 22-year-old patient presenting with left femoral exostosis revealed by an acute ischemia of the lower limb. Clinical examination of the contralateral limb was without abnormality. Computed tomography angiography revealed a thrombosed aneurysm of the supra articular popliteal artery associated to an exostosis of the lower extremity of the femur. Surgical treatment was recommended in this patient: resection of the popliteal aneurysm associated with a end-to-end suture of the popliteal artery and resection of bone exostosis.
