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 ...
The name is derived from the fact that the cells undergoing this form of cell death increase in size . It is generally considered a form of apoptosis , [ 1 ] and is a descriptor used in the context of inflamed fatty liver ( steatohepatitis ) [ 2 ] (which may be due to obesity or alcohol ), as well as viral hepatitis.
Cirrhosis, also known as liver cirrhosis or hepatic cirrhosis, chronic liver failure or chronic hepatic failure and end-stage liver disease, is an acute condition of the liver in which the normal functioning tissue, or parenchyma, is replaced with scar tissue and regenerative nodules as a result of chronic liver disease.
Treatment of hepatomegaly varies with the cause, so accurate diagnosis is the first concern. In auto-immune liver disease, prednisone and azathioprine may be used for treatment. [3] In lymphoma the treatment options include single-agent (or multi-agent) chemotherapy and regional
Chronic liver disease in the clinical context is a disease process of the liver that involves a process of progressive destruction and regeneration of the liver parenchyma leading to fibrosis and cirrhosis. [1] "Chronic liver disease" refers to disease of the liver which lasts over a period of six months.
Doppler ultrasound of the liver is typically utilized to confirm or suggest the diagnosis. Common findings on liver doppler ultrasound include increased phasicity of portal veins with eventual development of portal flow reversal. The liver is usually enlarged but maintained normal echogenicity. A liver biopsy is required for a definitive diagnosis.
A cavernous liver hemangioma or hepatic hemangioma is a benign tumor of the liver composed of large vascular spaces lined by monolayer hepatic endothelial cells. It is the most common benign liver tumour, and is usually asymptomatic and diagnosed incidentally on radiological imaging or during laparotomy for other intra-abdominal issues.
Apoptosis of the liver of a mouse. Hepatocytes are the liver's primary parenchymal cells, forming 80% of the liver's mass and 60% of its cells. They are round in shape and contain a nucleus and organelles that contribute to metabolic and secretory functions. [5] Hepatocytes also play a pivotal role in liver inflammation. [6]
