Abstract

Purpose: to describe the characteristics of hepatoblastoma (HB) on 2 detector computed tomography (CT) images.
Materials and method: 49 under 15 year-old patiens with pathological results of HB were undergone 2 detector computed
tomography from 2010 to 2014.
Result: 100% was solid tumor, the average diameter was 8.48mm, most of them were single tumor, located at the right lobe,
lobulated and defined margin, heterogeneous structure, 31.5% had calcification, strong contrast enhancement in the arterial phase, less than liver parenchyma in the portal phase. 63% enhanced less than normal liver parenchyma in both aterial and portal phase. Pretext II and III is 81.7%, lung metastasis in 4 cases, portal vein thrombosis in 2 cases, 4 cases infiltrated to extra-hepatic spaces, 1 tumor was ruptured, 2 caseshad hepatic umbilical nodes.
Conclusion: HB appears on CT images as a solid tumor, heterogeneous, irregular margin mass, 31.5% had calcification. After injecting the material contrast most of tumors enhance trongly during the arterial phase and less density than the surrounding liver parenchyma in the portal phase. The most common is PRETEXT II and III. It may metastase to lung, lead to portal vein thrombosis, hepatic hilar lymph node.
