Hepatomegaly is the condition of having an enlarged
liver. It is a nonspecific medical sign having many causes, which can broadly be broken down into infection, direct toxicity, hepatic tumours, or metabolic disorder. Often, hepatomegaly will present as an abdominal mass. Depending on the cause, it may sometimes present along with jaundice.
After a thorough
medical historyand physical examination, blood tests should be drawn. An important series of blood tests are the liver function tests, which give a good impression of the patient's broad metabolic picture.
ultrasoundof the liver can reliably detect a dilated biliary ductsystem, which helps distinguish parenchymal liver disease from extrahepatic bile duct obstruction. Ultrasound can also detect the characteristic texture of a cirrhotic liver, and can guide fine needle aspirationof cysts, abscesses and tumours. Computed tomography(CT) can help obtain more accurate anatomical information, and is unaffected by the obesityor the presence of bowel gases.

Hepatitis(Although not all hepatitis viruses cause hepatomegaly)
Liver abscess(pyogenic abscess and amoebic abscess)
