A liver metastasis is a malignant tumor in the liver that has spread from another organ that is affected by cancer. The liver is a common site for metastatic disease because of its rich, dual blood supply (the liver receives blood via the hepatic artery and portal vein). Metastatic tumors in the liver are 20 times more common than primary liver ...
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 tumors. [7] Liver transplantation is a treatment option for some patients. [7]
Hemosiderin deposition in the liver is a common feature of hemochromatosis and is the cause of liver failure in the disease. Selective iron deposition in the beta cells of pancreatic islets leads to diabetes [4] [2] due to the distribution of transferrin receptor on the beta cells of islets [3] and in the skin leads to hyperpigmentation.
Liver tumor types by relative incidence in adults in the United States (liver cancers in dark red color). [14] The most frequent liver cancer, accounting for approximately 75% of all primary liver cancers, is hepatocellular carcinoma (HCC). [15] HCC is a cancer formed by liver cells, known as hepatocytes, that become malignant. In terms of ...
Optimally, these scans are performed with intravenous contrast in multiple phases of hepatic perfusion to improve detection and accurate classification of any liver lesions. Due to the characteristic blood flow pattern of HCC tumors, a specific perfusion pattern of any detected liver lesion may conclusively detect an HCC tumor.
Transarterial bland embolization (TAE, also known as HAE) is a catheter-based tumor treatment of the liver.In this procedure, embolizing agents (e.g., polyvinyl alcohol, gelfoam, acrylic copolymer gelatin particles, embospheres) can be delivered through the tumor's feeding artery in order to completely occlude the tumor's blood supply.
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.
Hepatoblastoma is a malignant liver cancer occurring in infants and children and composed of tissue resembling fetal liver cells, mature liver cells, or bile duct cells. They usually present with an abdominal mass. The disease is most commonly diagnosed during a child's first three years of life. [1]
