Intravascular lipoma of the left common femoral vein

Lipomatous tumors of the heart and major central veins are unusual pathologic findings. We report an intravascular lipoma arising directly from the wall of the left common femoral vein (LCFV) in a patient who had progressive left leg swelling and in whom a deep venous thrombosis in the LCFV was initially diagnosed. this is the first case report if such a tumor in the literature. the computed tomography, magnetic resonance imaging, and intraoperative features are presented. the procedure of tumor excision and venous reconstruction with a cadaveric allograft is described.
