BACKGROUND Hepatocellular carcinoma (HCC) is the fifth most common neoplasia in the world. In the past, treatment of advanced HCC with conventional antineoplastic drugs did not result in satisfactory outcomes: recently, in this patient population the oral multikinase inhibitor sorafenib has been able to induce a statistically significant improvement of overall survival. Similarly to other anti-...

Early-enhancing areas that are perfusion abnormalities rather than tumor deposit are sometimes encountered on arterial dominant-phase images in multisection dynamic magnetic resonance imaging. Focal sparing in diffusely fatty liver is also a well recognized entity. However, both conditions occasionally create problems in the diagnosis of hepatic mass lesions. Familiarity with these abnormalitie...

A 53-year-old man was admitted to our hospital with abdominal pain. He had undergone surgery for a pancreatic pseudocyst related to chronic alcoholic pancreatitis 7 years previously at another hospital. Magnetic resonance imaging (MRI) 3 years later had shown a cystic lesion, 4cm in diameter, at the hepatic hilum, with two small mural nodules. The patient was then lost to follow-up for 3 years....

Nonfocal liver biopsy may be required to diagnose or stage diffuse parenchymal dis• ease such as cirrhosis, viral hepatitis, autoimmune hepatitis, primary biliary cirrhosis, primary sclerosing cholangitis, hemachromatosis, and Wilson’s disease. Focal liver biopsy may be necessary to diagnose or stage primary or secondary hepatic • malignancy and to differentiate malignancy from benign hepatic m...

Percutaneous image-guided ablation is performed throughout many areas of the body for various pathologies including hepatic malignancies. Heat and cold-based ablative technologies are effective and well-tolerated with an acceptable safety profile. However, ablative therapies may be technically more challenging and cause collateral thermal injury if the targeted lesion is adjacent to critical or...

Hepatic pseudolesions are defined as non-neoplastic focal abnormalities of the liver which can mimic or conceal true lesions. It is particularly common in due to its unique dual blood supply and existence multilevel anastomosis between them. Because recent advances CT MRI technology, they being increasingly encountered daily practice. Broadly be categorised (1) Focal parenchymal like fatty chan...

A 30-year-old woman presented with hepatomegaly and an audible hepatic bruit at 24 weeks gestation. Non-contrast MRI demonstrated an exophytic 12.6 x 7.8 x 12.8 cm mass arising from the right lobe of the liver with a central scar, suggestive of focal nodular hyperplasia (FNH). Conservative management included monthly abdominal ultrasound examinations until the time of delivery, to assess growth...
