Popliteal venous aneurysms have always been linked to death from pulmonary embolism. Incidental finding of an asymptomatic popliteal venous aneurysm during duplex scan performed for patients with chronic venous disease is increasingly diagnosed but the relation between popliteal venous aneurysms and chronic venous disease remains unknown. We report the incidental finding of three asymptomatic popliteal venous aneurysms associated with iliac vein compression in patients with chronic venous disease who had undergone computed tomography venography with direct pedal contrast injection. An association between popliteal venous aneurysms and iliac vein compression is postulated.
