Budd-Chiari syndrome refers to the clinical picture that occurs when there is partial or complete hepatic venous outflow obstruction. It is characterised on imaging by ascites, caudate hypertrophy, peripheral atrophy, and prominent collateral veins. Epidemiology Budd-Chiari syndrome is rare. ...
Cholangiocarcinoma is a malignant tumour arising from cholangiocytes in the biliary tree. It tends to have a poor prognosis and high morbidity. It is the second most common primary hepatic tumour, with intrahepatic cholangiocarcinomas (ICCs) accounting for 10-20% of primary liver tumours. Epide...
Cirrhosis is the common endpoint of a wide variety of chronic liver disease processes which cause hepatocellular necrosis. Cirrhosis can be diagnosed with ultrasound, CT, and MRI, and these imaging modalities can also be used to evaluate for possible complications of cirrhosis, such as portal hy...
Focal hepatic steatosis
Focal hepatic steatosis is common and seen in a number of clinical settings, essentially the same as those that contribute to diffuse hepatic steatosis: diabetes mellitus obesity alcohol abuse exogenous steroids drugs (amiodarone, methotrexate, chemotherapy) IV hyperalimentation In genera...
Haemochromatosis is an iron overload disorder characterised by a progressive increase in total body iron stores and deposition of iron in some non-reticuloendothelial system (RES) body organs which results in some instances in organ dysfunction. This article focus on the general principles of h...
Hepatocellular carcinoma (HCC) is the most common primary malignancy of the liver. It is strongly associated with cirrhosis, from both alcohol and viral aetiologies. HCC constitutes approximately 5% of all cancers partly due to the high endemic rates of hepatitis B infection 1. Epidemiology HC...
Hypervascular liver lesions
Hypervascular liver lesions may be caused by primary liver pathology or metastatic disease. Differential diagnosis Primary lesions hepatocellular carcinoma (HCC) most common hypervascular primary liver malignancy early arterial phase enhancement and then rapid wash out rim enhancement of c...
Mallory bodies are cytoplasmic eosinophylic inclusions in hepatocytes, associated with ballooning and inflammation, found in: alcoholic fatty liver disease and hepatitis non-alcoholic fatty liver disease hepatocellular carcinoma (HCC) primary biliary cirrhosis (PBC) cholestasis
Portal hypertension is defined as portal venous pressure greater than 12 mmHg. Pathology Causes can be split in their relation to the hepatic sinusoids: pre-sinusoidal portal vein thrombosis extrinsic compression of portal vein Schistosomiasis (S. mansoni or S. japonicum) sinusoidal cirr...
Hepatic hydatid infection
Hepatic hydatid disease is a parasitic zoonosis caused by the Echinococcus tapeworm. In the liver, two agents are recognised as causing disease in humans: Echinococcus granulosus Echinococcus multilocularis For a general discussion, and for links to other system-specific manifestations, plea...
Variant hepatic arterial anatomy
Variation in hepatic arterial anatomy is seen in 40-45% of people. Classic branching of the common hepatic artery from the coeliac artery, and the proper hepatic artery into right and left hepatic arteries to supply the entire liver, is seen in 55-60% of the population. Terminology An accesso...
The liver is the largest abdominal organ that plays a major role in metabolism and has a number of functions, including glycogen storage, decomposition of red blood cells, plasma protein synthesis, hormone production, and detoxification. It is one of the very few organs that has the ability to r...
The falciform ligament is a broad and thin peritoneal ligament. It is sickle-shaped (Latin: "falciform") and a remnant of the ventral mesentery of the fetus. It is situated in an anteroposterior plane but lies obliquely so that one surface faces forward and is in contact with the peritoneum beh...
Hepatomegaly refers to an increase in size or enlargement of the liver. Pathology Aetiology Hepatomegaly can result from a vast range of pathology including, but not limited to, the following: malignancy/cellular infiltrate multiple metastases lymphoma(s) leukaemia(s) hepatocellular car...

Focal nodular hyperplasia
Focal nodular hyperplasia (FNH) is a regenerative mass lesion of the liver and the second most common benign liver lesion (most common is a haemangioma). Many FNHs have characteristic radiographic features on multimodality imaging, but some lesions may be atypical in appearance. FNHs are typical...

Focal fatty sparing of the liver
Focal fatty sparing of the liver is the localised absence of increased intracellular hepatic fat, in a liver otherwise fatty in appearance i.e. diffuse hepatic steatosis. Recognition of this finding is important to prevent the erroneous belief that the region of sparing is itself a mass. Epidem...
Diffuse hepatic steatosis
Diffuse hepatic steatosis, also known as fatty liver, is a common imaging finding and can lead to difficulties assessing the liver appearances, especially when associated with focal fatty sparing. Terminology The term 'fatty infiltration of the liver' is often erroneously used to describe live...
