It … Fibrosis means that healthy liver tissue is starting to be replaced by scar tissue, hardening the liver and interfering with its functions. Owing to its low prevalence, even in advanced cirrhosis, the right posterior hepatic notch sign is of little value in the diagnosis of cirrhosis due to chronic hepatitis B virus infection, whereas an expanded gallbladder fossa could be used as a non-specific indicator of early fibrosis before the gross appearance of advanced hepatic fibrosis. Sonographic Evaluation of Liver Cirrhosis: Causes and Pathophysiology.

This tumor is the sixth most common malignancy worldwide and the third most common cause of cancer related death. prolonged obstruction of the extrahepatic biliary tree resulting in fibrosis of the liver leading to cirrhosis. secondary biliary cirrhosis gross appearance. Cirrhosis is classified as either compensated or decompensated. This is where cell death (necrosis) occurs throughout whole areas of the liver called hepatic lobules. The gross morphologic appearance of a cirrhotic liver is categorized by the size of the parenchymal nodules: micronodular, macronodular, or mixed. Regenerating nodules (RNs): These regenerating hepatocytes are surrounded by fibrotic septae. Procedures for grossing liver explants will vary between institutions. The gross appearance of a native liver with PBC (A) is different from an allograft failing from chronic rejection (B). viral hepatitis) is dealt with in the medical liver disease article. 3A). Abdominal ultrasonography with Doppler is a noninvasive, widely available modality that provides valuable information regarding the gross appearance of the liver and blood flow in the portal and hepatic veins in patients suspected to have cirrhosis. The gross appearance is often very distinct from the background liver, even in the presence of cirrhosis. The regenerative hepatocyte nodules average less than 3 mm in size. This results in a mottled pattern of contrast enhancement in the arterial and early portal venous phase with decreased enhancement of the liver periphery.
