Hepatomegaly is enlargement of the liver. [4] It is a non-specific medical sign , having many causes, which can broadly be broken down into infection , hepatic tumours , and metabolic disorder . Often, hepatomegaly presents as an abdominal mass .
The liver span is a measurement performed during physical examination to determine the size of the liver and identify possible hepatomegaly.. It is the distance between the lower border of the liver in the mid-clavicular line obtained by palpation, and the upper border of the liver in the mid-clavicular line detected by percussion (the upper border of the liver lies behind the ribs and can not ...
Hepatomegaly Medical imaging : Longitudinal axis > 15.5 cm at the hepatic midline, or > 16.0 cm at the midclavicular line [ 14 ] Autopsy : Weight over upper limit of standard reference range, of 1,860 g (4.10 lb) in men [ 12 ] and 1,770 g (3.90 lb) in women.
Signs and symptoms of liver masses vary from being asymptomatic to patients presenting with an abdominal mass, hepatomegaly, abdominal pain, jaundice, or some other liver dysfunction. Treatment varies and is highly specific to the type of liver tumor. [3]
Cirrhosis, also known as liver cirrhosis or hepatic cirrhosis, chronic liver failure or chronic hepatic failure and end-stage liver disease, is a condition of the liver in which the normal functioning tissue, or parenchyma, is replaced with scar tissue and regenerative nodules as a result of chronic liver disease.
Inflammatory cytokines (TNF-alpha, IL-6 and IL-8) are thought to be essential in the initiation and perpetuation of liver injury and cytotoxic hepatomegaly by inducing apoptosis and severe hepatotoxicity. One possible mechanism for the increased activity of TNF-α is the increased intestinal permeability due to liver disease.
Congestive hepatopathy, is liver dysfunction due to venous congestion, usually due to congestive heart failure.The gross pathological appearance of a liver affected by chronic passive congestion is "speckled" like a grated nutmeg kernel; the dark spots represent the dilated and congested hepatic venules and small hepatic veins.
Patients with Mauriac syndrome may present with obesity, hepatomegaly, cushingoid facies, and elevated liver enzymes. Patients usually have growth failure and delayed puberty, which should warn the physician about insufficient management of the patient's diabetes. These symptoms can be reversed with good glycemic control. [3] [4] [5]
