My father's (age 58) usg test shows: 1. Liver is enlarged in size, shape and fatty (15. 76 cm). 2.parenchymal echotexture is raised. 3.no focal abnormality not seen. Intra hepatic biliary channels are not dilated. 4.portal vein (1 cm) is normal in caliber at the porta hepatis. Please suggest what to do. Is it something too bad or not?
