A 31-year-old man admitted to our hospital was diagnosed as having of fulminant hepatitis(type A). Upon admission ultrasonography revealed a thickening of the gallbladder wall, the disappearance of gallbladder cavity, a uniform echo pattern of the parenchyma and no enlargement of the liver. Four months after admission, the thickness of the gallbladder wall improved, as did the irregularity of liver surface, the coarse echo pattern of the hepatic parenchyma and the gallstone. Histological findings on liver tissue samples revealed active stage of liver cirrhosis. And endscopic examination revealed esophageal varices [Cw, F1, Li RC-sign(-)]. Furthermore, over the course of disease, we observed that the Spleen Index gradually increased, while the portal blood flow volume decreased.
