Results The findings of CT were: on plain scan, there was mix density inside the liver with obscure boundary, the liver and spleen were surrounded by liquid in five cases. Inhomogeneous enhanced tumor tissues were demonstrated at arterial phase. Capsula and cleft were seen in one case, and five with mix density. Embolus in portal vein was noted in two.
