In chronic hepatitis and cirrhosis and other chronic liver disease can also be seen splenomegaly. There have been no reports of splenomegaly about asymptomatic HBsAg carriers. The authors used ultrasound tomography to measure spleen size and found that HBsAg carriers had a significantly larger spleen than HBsAg-negative ones. HBsAg carriers were identified at least 2 times to find HBsAg positive, a total of 314 cases, and the other
