Examination requested for follow-up. A 3x2cm enhancing lesion is within the posterior segment of the right hepatic lobe has a vascular connection to the right hepatic vein and right posterior branch of the portal vein. An additional venous collateral vessel is adjacent to the right hepatic vein. No other hepatic lesions are otherwise identified. The spleen is enlarged and measures 17.5cm cranio-caudad by 12.5cm length by 6.0cm width which yields a splenic index of 1312.5 cubic centimeters. No focal splenic lesions are otherwise identified. No evidence of adenopathy, free fluid or inflammatory change within either the abdomen or pelvis. Except for a small hiatal hernia, the remainder of the abdominal and pelvic organs are within normal limits.
