A Case of Adventitial Cystic Disease of the Common Femoral Vein for Which Ultrasoundsonography Was Useful for Its Diagnosis

Abstract

A woman in her 60s had admitted to her family doctor for left lower extremity edema. She was consulted to our hospital. CT scan showed a mass lesion which compressing with the left common femoral vein. There was no thrombus but a mass lesion near the left common femoral vein (23×13×6 mm) by the ultrasoundsonography. The mass lesion was not deformed by the compression test with ultrasound probe. The mass lesion showed low or isoechoic ultrasonic characters with partition wall inside. MRI showed a multifocal cystic structure suggesting a benign tumor such as lymphangioma or adventitial cystic disease. The patient was diagnosed as a femoral venous stenosis due to the compression of adventitial cystic disease. A surgical resection was performed and the pathological findings showed multifocal cyst, which coincidence with the adventitial cystic disease. Venous adventitial cystic disease is rare, only 5% of all cases. Here we report a rare case of venous adventitial cystic disease precisely detected by the ultrasoundsonography.
