Fig. 10D 36-year-old man with primary thrombocythemia developed
chronic Budd-Chiari syndrome that required transjugular intrahepatic
portosystemic shunt (TIPS) placement. Patient has multiple benign nodules
largely followed without changes. Helical CT after IV contrast injection
displays enhancing nodule (arrows) surrounded by low-attenuating area
related to vascular disorders. On helical CT, benign regenerative nodules are
homogeneously hyperattenuating on arterial phase and remain slightly
hyperattenuating on portal vein phase.
