Popliteal Venous Aneurysm: A Case of Completely Thrombosed Popliteal Venous Aneurysm

Abstract

A 73-year-old man with completely thrombosed popliteal venous aneurysm is reported. The patient was first seen with acute pulmonary embolism. Then he returned to our hospital with localized swelling and pain in the left popliteal fossa.

Preoperative investigation including duplex scanning and magnetic resonance imaging, this was diagnosed as a benign soft tissue cyst. Surgical resection was performed and operation revealed a saccular aneurysm of the left popliteal vein, which was completely thrombosed. Postoperative course was uneventful.

Although popliteal venous aneurysms are rare, care should be taken whenever diagnosing a soft tissue popliteal fossa mass or looking for the cause of recurrent pulmonary embolism.
