The abdominal CT study shows an extensive hypodense mass centered in the right liver, with an estimated volume over 7,000 cc. The mass contains thick septa and solid nodular elements, and results in right hydronephrosis due to ureteral compression. The C+ delayed phase shows slight enhancement of the septa and nodular elements. Retroperitoneal and mesenteric lymph nodes were detected. No evidence of portal venous thrombosis was seen.
