From: Tumor in the veins: an abdominal perspective with an emphasis on CT and MR imaging
A 33-year-old female who underwent laparoscopic myomectomy 2 months ago now presents with right lower extremity edema, shortness of breath, and mild abdominal pain. a Color Doppler US image demonstrates thrombus within the lumen of the right common iliac vein (asterisk). b Axial plane postcontrast CT image shows tubular structures (arrows) in the pelvis suggestive for thrombosed adnexal veins. c Coronally reformatted postcontrast CT image of the same patient demonstrates thrombus in the right gonadal vein (arrows) and right common iliac vein (arrowheads). Thrombus was also noted in the hepatic and suprahepatic segments of the IVC (dotted arrows) with extension into the right atrium. d The tumor thrombus within the right atrium (arrow) is better appreciated on axial postcontrast image. Findings were found to be suggestive for intravascular leiomyomatosis, which was confirmed after histopathological exam of the pathologic specimen
