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 ...
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.
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]
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 ...
Chronic liver disease takes several years to develop and the condition may not be recognised unless there is clinical awareness of subtle signs and investigation of abnormal liver function tests. Testing for chronic liver disease involves blood tests, imaging including ultrasound, and a biopsy of the liver. The liver biopsy is a simple ...
Liver cell adenomatosis is also associated with becoming hepatocellular carcinoma. [11] Like hepatic adenomas, they are diagnosed with imaging and biopsies as needed. Treatment of liver cell adenomatosis is difficult due to the multiple, widespread lesions. Liver imaging should be reviewed to see if it is possible to surgically remove the ...
On ultrasound, HCC often appears as a small hypoechoic lesion with poorly defined margins and coarse, irregular internal echoes. When the tumor grows, it can sometimes appear heterogeneous with fibrosis, fatty change, and calcifications. This heterogeneity can look similar to cirrhosis and the surrounding liver parenchyma.
Cytology is the name given to the branch of biology that deals with the formation, structure and functionality of the cells. [1] Liver cytology specializes in the study of liver cells. The main liver cells are called hepatocytes; however, there are other cells that can be observed in a liver sample such as Kupffer cells (macrophages). [2]
