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 ...
Abdominal ultrasonography of the liver, as a sagittal plane through the midclavicular line, with some standard measurements [2] Right lobe of the liver at the midclavicular line at ages 0 to 7 [16] Suspicion of hepatomegaly indicates a thorough medical history and physical examination, wherein the latter typically includes an increased liver span.
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.
Fatty liver disease (FLD), also known as hepatic steatosis and steatotic liver disease (SLD), is a condition where excess fat builds up in the liver. [1] Often there are no or few symptoms. [1] [2] Occasionally there may be tiredness or pain in the upper right side of the abdomen. [1] Complications may include cirrhosis, liver cancer, and ...
Increased pressure in the sublobular branches of the hepatic veins causes an engorgement of venous blood, and is most frequently due to chronic cardiac lesions, especially those affecting the right heart (e.g., right-sided heart failure), the blood being dammed back in the inferior vena cava and hepatic veins.
In histo pathology, ballooning degeneration, formally ballooning degeneration of hepatocytes, is a form of liver parenchymal cell (i.e. hepatocyte) death. The name is derived from the fact that the cells undergoing this form of cell death increase in size ( balloon ).
The liver parenchyma is the functional tissue of the organ made up of around 80% of the liver volume as hepatocytes. The other main type of liver cells are non-parenchymal. Non-parenchymal cells constitute 40% of the total number of liver cells but only 6.5% of its volume. [11]
In patients with deranged liver function tests, ultrasound may show increased liver size (hepatomegaly), increased reflectiveness (which might, for example, indicate cholestasis), gallbladder or bile duct diseases, or a tumor in the liver. Ultrasonography of liver tumors involves two stages: detection and characterization.
