A Case Report of Primary Venous Aneurysm of Greater Saphenous Vein Retarded of Preoperative Diagnosis

Abstract

We present a surgical case of primary venous aneurysm retarded of preoperative diagnosis. A 28-year-old man was admitted to our hospital, because a soft tumor in the left lower extremity had been growing. And he had noticed the tumor since ten years ago, but had no symptom or no history of trauma. An ultrasonic study revealed a cystic tumor without an active blood flow signal. Magnetic resonance imaging revealed a cystic tumor with a smooth outline adjacent to the greater saphenous vein. Arterial and venous angiography revealed no vascular area in the tumor. We had in mind whether dealing with a soft tissue tumor or not. The tumor was excised successfully and the jelly-like coagulation of blood is choked up in the tumor and a blood flow was not seen into it. But, the greater saphenous vein and tumor are continuing, and the outflow and inflow vein could be checked. That was the image which does not have inconsistency as venous anemysm histologically.
