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 ...
Liver tumors (also known as hepatic tumors) are abnormal growth of liver cells on or in the liver. Several distinct types of tumors can develop in the liver because the liver is made up of various cell types. [1] Liver tumors can be classified as benign (non-cancerous) or malignant (cancerous) growths.
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.
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]
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.
Cut surface of a liver showing multiple paler metastatic nodules originating from pancreatic cancer. Initially, nearby lymph nodes are struck early. [10] The lungs, liver, brain, and bones are the most common metastasis locations from solid tumors. [10] In lymph node metastasis, a common symptom is lymphadenopathy
Estimates based on most recent data suggest that each year there are 841,000 new liver cancer diagnoses and 782,000 deaths across the globe. [55] Liver cancer is the most common cancer in Egypt, the Gambia, Guinea, Mongolia, Cambodia, and Vietnam. [55] In terms of gender breakdown, globally liver cancer is more common in men than in women. [43 ...
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).
