Abstract
Adventitial cystic disease of the vein is a rare vascular disease. Herein, we report a case of adventitial cystic disease of the common femoral vein that was initially misdiagnosed as deep venous thrombosis in a 41-year-old male who presented with leg swelling. We focused on the imaging findings and compared them with those of deep venous thrombosis. CopyrightsEntities:

Fig. 1Adventitial cystic disease of the right common femoral vein in a 41-year-old male.
A, B. Initial transverse (A) and longitudinal (B) color Doppler ultrasonography images show a dilated vein and a hypoechoic lesion (V) without vascularity, which was misdiagnosed as deep venous thrombosis.
C, D. A gray-scale image (C) and color Doppler ultrasonography (D) acquired after 3 years show a 2.7 cm × 2.1 cm-sized expansile anechoic lesion (V) without color flow but with posterior acoustic enhancement in the lumen of the right common femoral vein. Developed collateral veins are also observed (arrows).
E. Axial CT demonstrates the dilatation of the right common femoral vein due to an intraluminal well-defined ovoid low attenuated mass (V) and adjacent well-developed collaterals.
F. Histologic findings of a cystic mass show that the epicenter is adventitial, and that it consists of multilocular cystic spaces (arrows) filled with amorphous acellular proteinous fluid (hematoxylin and eosin stain, × 10).
