(a) Collapsed right-sided common femoral vein (white arrow) due to massive hematoma (yellow arrows). (b) Nonocclusive thrombus in right-sided midpopliteal vein, compared to patient left-sided midpopliteal vein (white arrows).

This study also demonstrated severe stenosis of the right superficial femoral vein secondary to extrinsic compression with nonocclusive wall adherent thrombus in the right midpopliteal vein (Figure 1).

Partially thrombosed (white arrows) right common femoral vein. (a) is without compression; (b) is with compression, which demonstrates incomplete collapse of the RCFV.

Ultrasound was ordered for suspected pseudoaneurysm but instead demonstrated nonocclusive thrombus within the right common femoral vein without evidence of hematoma or arterial pathology (Figure 2).
MIP (maximal intensity projection) and 3D cinematic rendering images of the CT venogram performed 1 month after the ultrasound exam were normal, with no evidence of residual venous thrombus or traumatic pseudoaneurysm.

Interestingly, he did report resolution of his groin pain and ipsilateral edema, and follow-up CT venogram one month later revealed thrombus resolution (Figure 3).
