Focal nodular hyperplasia is a benign tumor of the liver (hepatic tumor), which is the second most prevalent tumor of the liver after hepatic hemangioma. [1] It is usually asymptomatic, rarely grows or bleeds, and has no malignant potential. [2]
Nodular regenerative hyperplasia (NRH) is a rare liver disease, characterised by the growth of nodules within the liver, resulting in liver hyperplasia.While in many cases it is asymptomatic and thus goes undetected – or is only discovered incidentally while investigating some other medical condition – in some people it results in non-cirrhotic portal hypertension (NCPH).
Hepatic adenoma is usually detected by imaging, typically an ultrasound or CT, as a hyperenhancing liver nodule.Given that several liver tumors appear similarly on these imaging modalities, a multi-phase contrast-enhanced imaging study such as CT or MRI may be used to provide more information.
There are several types of benign liver tumors. They are caused by either abnormal growth of neoplastic cells or in response to liver injury, known as regenerative nodules. [2] One way to categorize benign liver tumors is by their anatomic source, such as hepatocellular, biliary, or stromal. [2]: 693–704
Benign liver tumors generally develop on normal or fatty liver, are single or multiple (generally paucilocular), have distinct delineation, with increased echogenity (hemangiomas, benign focal nodular hyperplasia) or absent, with posterior acoustic enhancement effect (cysts), have distinct delineation (hydatid cyst), lack of vascularization or show a characteristic circulatory pattern ...
Macroscopically, liver cancer appears as a nodular or infiltrative tumor. The nodular type may be solitary (large mass) or multiple (when developed as a complication of cirrhosis). Tumor nodules are round to oval, gray or green (if the tumor produces bile), well circumscribed but not encapsulated.
U.S. Surgeon General Dr. Vivek Murthy said Friday that there is a direct link between alcohol consumption and increased risk for cancer, including cancers of the breast, esophagus, liver and ...
High grade dysplastic nodules are precancerous lesions of the liver. Within two years, there is a risk for cancer arising from these nodules of 30–40%. [44] Obesity and metabolic syndrome have emerged as an important risk factor, as they can lead to steatohepatitis. [30] [45] Diabetes increases the risk for HCC. [45] [39]
