A young male patient ruffering from of multiple exostoses was referred for soft, painless slowly growing mass in the popliteal fossa, accompanied by calf edema. There was no trauma. Fluid collection adjacent to the superficial femoral artery with thrombosis and signs of AV shunt were detected during ultrasound investigation. MRI confirmed the conclusions from ultrasound. Exostosis of the distal femoral metaphysis with active cartilaginous cap was found very close to the fluid collection. CT angiography detected pseudoaneurysm without AV shunt and very intimate connection between fluid collection and the cartilaginous cap. DSA confirmed a pseudoaneurysm like as the ultrasound and CT angiography previously. Fluid collection is comes from the superficial femoral artery and it is drained back to it. Blood flow in the superficial femoral vein is interrupted by compression of fluid collection.
