Hepatomegaly

Hepatomegaly is the condition of having an enlarged liver. It is a non-specific medical sign having many causes, which can broadly be broken down into infection, hepatic tumours, or metabolic disorder. Often, hepatomegaly will present as an abdominal mass. Depending on the cause, it may sometimes present along with jaundice.

Symptoms/signs

Symptoms having to do with hepatomegaly can include several, among them the individual may experience some weight loss, poor appetite and lethargy (jaundice and bruising may also be present)

Causes

Among the causes of hepatomegaly are the following:

Mechanism

The mechanism of hepatomegaly consists of vascular swelling, inflammation (due to the various causes that are infectious in origin) and deposition of (1) non-hepatic cells or (2) increased cell contents (such due to iron in hemochromatosis or hemosiderosis and fat in fatty liver disease)

Diagnosis

Suspicion of hepatomegaly indicates a thorough medical history and physical examination, wherein the latter typically includes an increased liver span. Blood tests should be done, importantly liver-function series, which will give a good impression of the patient's broad metabolic picture.

A complete blood test can help distinguish intrinsic liver disease from extrahepatic bile-duct obstruction. An ultrasound of the liver can reliably detect a dilated biliary-duct system, it can also detect the characteristics of a cirrhotic liver,.Computerized tomography (CT) can help to obtain accurate anatomical information, in individuals with hepatomegaly.

Treatment

Treatment of hepatomegaly will vary depending on the cause of the liver enlargement and hence accurate diagnosis is the primary concern. In the case of auto-immune liver disease, prednisone and azathioprine may be used for treatment.

In the case of lymphoma the treatment options include single-agent (or multi-agent) chemotherapy and regional radiotherapy, also surgery may be an option in specific situations.Meningococcal group C conjugate vaccine are also used in some cases.

In primary biliary cirrhosis ursodeoxycholic acid helps the bloodstream remove bile which may increase survival in some affected individuals.
