Leiomyosarcoma of the popliteal vein.
Primary vascular leiomyosarcomas are rare tumors arising from the media of vessel walls, involving the extremities in about one third of reported cases, and the popliteal vein even less frequently. We report a case of popliteal vein leiomyosarcoma in a 62-year old man who presented with leg pain and edema 4 weeks following spine surgery. Findings on ultrasound, MRI and CT angiography are reviewed, with particular emphasis on the value of CT angiography in fully evaluating the extent of the mass and in assisting percutaneous biopsy.
