== Overview ==
The '''liver''' is an [[Organ (anatomy)|organ]] present in [[Vertebrate|vertebrates]] and some other animals. The adult human liver normally weighs between 1.4 to 1.6 kilograms (3.1 to 3.5 pounds), and it is a soft, pinkish-brown "boomerang shaped" organ. It is located on the right side of the upper [[Human abdomen|abdomen]] below the [[Diaphragm (anatomy)|diaphragm]]. The size of the liver increases with age and ranges between 5 cm to 15 cm in adulthood. A normal liver is less than 16 cm on ultrasound evaluation. Hepatomegaly may be found during physical examination or on imaging studies. Imaging is more accurate in determining liver size.<ref name="pmid475535">{{cite journal| author=Sapira JD, Williamson DL| title=How big is the normal liver? | journal=Arch Intern Med | year= 1979 | volume= 139 | issue= 9 | pages= 971-3 | pmid=475535 | doi= | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=475535  }} </ref><ref name="pmid6622701">{{cite journal| author=Niederau C, Sonnenberg A, Müller JE, Erckenbrecht JF, Scholten T, Fritsch WP| title=Sonographic measurements of the normal liver, spleen, pancreas, and portal vein. | journal=Radiology | year= 1983 | volume= 149 | issue= 2 | pages= 537-40 | pmid=6622701 | doi=10.1148/radiology.149.2.6622701 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=6622701  }} </ref> In some conditions normal liver may be palpated as enlarged liver including thin people, during deep [[Inhalation|inspiration]], right [[pleural effusion]], and [[emphysema]] resulting in hyperinflation of the chest with diaphragmatic descent and downward displacement of the [[liver]].

'''Hepatomegaly''' is the condition of having an enlarged [[liver]]. It is a nonspecific [[sign (medicine)| medical sign]] having many causes, which can broadly be broken down into [[infection]], direct toxicity, hepatic tumors, or [[metabolic disorder]]. Often, hepatomegaly will present as an [[abdominal mass]]. Depending on the cause, it may sometimes present along with [[jaundice]].

==Diagnosis==
After a thorough [[medical history]] and [[physical examination]], [[blood test]]s should be drawn. An important series of blood tests are the [[liver function test]]s, which give a good impression of the patient's broad metabolic picture.
 
An [[ultrasound]] of the liver can reliably detect a dilated [[biliary duct]] system, which helps distinguish [[parenchyma]]l liver disease from extrahepatic bile duct obstruction. Ultrasound can also detect the characteristic texture of a [[liver cirrhosis|cirrhotic liver]], and can guide [[fine needle aspiration]] of [[cyst]]s, [[abscess]]es and tumors.
 
[[Computed tomography]] (CT) can help obtain more accurate [[anatomy|anatomical]] information, and is unaffected by the [[obesity]] or the presence of bowel gases.

Synonyms and keywords: Enlarged liver; liver enlargement

Overview

The liver is an organ present in vertebrates and some other animals. The adult human liver normally weighs between 1.4 to 1.6 kilograms (3.1 to 3.5 pounds), and it is a soft, pinkish-brown "boomerang shaped" organ. It is located on the right side of the upper abdomen below the diaphragm. The size of the liver increases with age and ranges between 5 cm to 15 cm in adulthood. A normal liver is less than 16 cm on ultrasound evaluation. Hepatomegaly may be found during physical examination or on imaging studies. Imaging is more accurate in determining liver size.[1][2] In some conditions normal liver may be palpated as enlarged liver including thin people, during deep inspiration, right pleural effusion, and emphysema resulting in hyperinflation of the chest with diaphragmatic descent and downward displacement of the liver. Common pathological causes that may result in hepatomegaly are hepatitis, storage disorders, impaired venous outflow, infiltrative disorders, and biliary obstruction.

Causes

Various causes of hepatomegaly may be classified on the basis of etiology into hepatitis, storage disorders, impaired venous outflow, infiltrative, and obstructive causes.[3][4][5][6][7][8][9][10][11][12][13][14]

Etiology Disease
Hepatitis Infections Acute and chronic viral hepatitis
Bacterial liver abscess
Parasitic infections
Granulomatous hepatitis
Ischemia Ischemic hepatitis ("shock liver")
Toxins Alcoholic hepatitis
Steatosis Alcoholic fatty liver disease
Nonalcoholic steatohepatitis
Medications Drug induced liver injury (DILI)
Immune mediated hepatitis Autoimmune hepatitis
Copper deposition Wilson disease
Storage disorders Glycogen Glycogen storage disorders
Diabetes mellitus
Lipid Gaucher disease
Nonalcoholic steatohepatitis
Protein Alpha-1 antitrypsin deficiency
Iron Hemochromatosis
Impaired venous outflow Cardiac Right heart failure
Constrictive pericarditis
Hepatic vein Hepatic vein thrombosis
Inferior vena cava web
Intrahepatic Sinusoidal obstruction syndrome
Peliosis hepatis
Infiltrative diseases Benign primary liver tumors Hemangiomas
Adenomas
Focal nodular hyperplasia
Malignant primary liver tumors Hepatocellular carcinoma
Cholangiocarcinoma
Fibrolamellar carcinoma
Hemangioendothelioma
Metastatic or disseminated tumors Myeloma
Lymphoma
Leukemia
Metastatic solid tumors
Biliary obstruction Primary biliary cirrhosis
Primary sclerosing cholangitis
Biliary atresia
Other Anatomic variations Riedel's lobe
Cystic liver disease Polycystic liver disease
Caroli's disease

Differential Diagnosis

Patients with hepatomegaly need to be differentiated from other patients presenting with similar complaints such as abdominal pain.[3][4][5][6][7][8][9][10][11][12][13][14]
