title: B-scan ultrasound in the diagnosis of popliteal aneurysms.
abstract: Sonography gives a characteristic picture of popliteal aneurysms, with an easily demonstrable connection of the sonolucent aneurysmal sac with the popliteal artery. It is a good screening procedure for suspected aneurysms and for patients with popliteal pain, mass, or sudden distal ischemia. Three case reports of five popliteal aneurysms diagnosed by ultrasound are presented. A case of neurofibrosarcoma occurring in the popliteal fossa is shown for comparison.
