Final answer:
The sonographic signs of chronic hepatitis include changes in liver echotexture, irregular liver surface, and splenomegaly, among others. Fever is generally not a sonographic sign and is not associated with chronic hepatitis.
Step-by-step explanation:
The question is asking to identify which of the listed options is not a sonographic sign of chronic hepatitis. The sonographic signs of chronic hepatitis typically include changes in liver echotexture irregular liver surface, and splenomegaly (enlarged spleen). Additionally chronic hepatitis may present with indirect signs such as ascites (accumulation of fluid in the abdomen) due to cirrhosis.
It is important to review the liver function tests as they will show elevated enzymes indicative of liver inflammation, such as alkaline phosphatase, alanine aminotransferase (ALT) and aspartate aminotransferase (AST). The exclusion of fever while not a sonographic sign is generally not associated with chronic hepatitis but rather with acute episodes or other complications. Therefore looking at the provided list, fever would likely be the correct answer as it is not a sonographic sign of chronic hepatitis.
