This is a case report of an athletic, middle-aged man with a remote history of penetrating right leg trauma who developed a pulmonary embolism, thrombosis of the popliteal vein, a mass in the popliteal fossa, and acute ischemia of the right lower leg. At operation a thrombosed pseudoaneurysm was found arising from a defect in the popliteal vein with extrinsic compression of the popliteal artery. The defect was patched with autogenous vein and the long-term result was excellent. Pseudoaneurysm of the popliteal vein is a previously unreported entity. Popliteal venous aneurysms usually begin with phlebitic or pulmonary thromboembolic manifestations and present a diagnostic challenge. Venous aneurysms in general are uncommon pathologic entities with a diverse etiology; the current etiologic concepts and classification are briefly discussed in the text. A new differential diagnosis for masses in the popliteal fossa is introduced by this report.
