  • Acute hepatitis E
  • Chronic viral hepatitis

Liver dysfunction in other infectious diseases

Other inflammatory liver diseases

Alcoholic liver disease

This may cause fatty liver, hepatitis, fibrosis and sclerosis leading to cirrhosis and finally hepatic failure.

Toxic liver disease

This includes mostly drug-induced hepatotoxicity, which may generate many different patterns over liver disease, including

Liver damage is part of Reye's syndrome.

Liver tumours

Malignant neoplasm of liver and intrahepatic bile ducts. The most frequent forms are metastatic malignant neoplasm of liver)

Benign neoplasm of liver include hepatic hemangiomas, hepatic adenomas, and focal nodular hyperplasia (FNH).

End-stage liver disease

Chronic liver diseases like chronic hepatitis, chronic alcohol abuse or chronic toxic liver disease may cause

Cirrhosis may also occur in primary biliary cirrhosis. Rarely, cirrhosis is congenital.

Metabolic diseases

Vascular disorders

Cysts

  • Congenital cystic disease of the liver
  • Cysts caused by Echinococcus
  • Hepatic cyst (liver cyst)

Others

Amyloid degeneration of liver

Gallbladder and biliary tract diseases

  • malignant neoplasm of the gallbladder
  • malignant neoplasm of other parts of biliary tract

Diagnosis

In hepatology, important signs and symptoms include:
