2-year-old male with hepatoblastoma status post cycles of chemotherapy. ABDOMEN:LIVER, BILIARY TRACT: Again seen is a large solid heterogeneously enhancing liver mass with lobulated contours occupying a majority of the left hepatic lobe measuring 4.6 x 6.9 x 5.1 cm, AP x transverse x craniocaudal (series 501, image 10; series 401, image 12). This is decreased in size compared to the prior study where this measured 6.8 x 8.3 x 10.3, TR x AP x CC. No intra-or extrahepatic biliary ductal dilatation.The right portal vein appears completely spared. The tumor is adjacent to the left portal and just distal to the division from the main portal vein. The left portal vein may not be distal to the tumor. The mass is supplied by several branches of the left hepatic artery. The hepatic veins appear spared.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: The kidneys enhance symmetrically. Kidneys excrete contrast symmetrically.RETROPERITONEUM, LYMPH NODES: No significant retroperitoneal or mesenteric lymphadenopathy.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
1.Large heterogeneously enhancing liver mass occupying a large portion of the left hepatic lobe known to be a hepatoblastoma is significantly decreased in size compared to the prior exam.2.No evidence of metastatic disease
