From: Tumor in the veins: an abdominal perspective with an emphasis on CT and MR imaging
A 62-year-old female with unremarkable medical history now presents with right upper quadrant pain and weight loss. a Abdominal US study shows a large, hypoechoic solid mass with ill-defined borders (arrows) at the liver hilum. b Coronal T2W MR image demonstrates an infiltrative, expansile mass within the main portal vein and its distal branches (arrows). c Axial plane postcontrast equilibrium phase T1W MR image demonstrates intense contrast enhancement of the mass (arrows) suggestive for a tumor thrombus over a bland thrombus. There were no associating imaging findings suggestive for parenchymal chronic liver disease or parenchymal HCC focus. Percutaneous image guided biopsy revealed portal vein leiomyosarcoma
