Causes, incidence, and risk factors
A hepatic hemangioma is the most common type of liver tumor that is not caused by cancer. It may be a birth defect.
Hepatic hemangiomas can occur at any time. They are most common in people in their 30s to 50s. Women get these tumors more often than men and the tumors are often bigger.
Babies may develop a type of hepatic hemangioma called benign infantile hemangioendothelioma. This is also called multinodular hepatic hemangiomatosis. This is a rare, noncancerous tumor that has been linked to high rates of heart failure and death in infants. Infants are usually diagnosed by the time they are 6 months old.
Some hemangiomas may cause bleeding or interfere with organ function. Most do not produce symptoms. In rare cases, the hemangioma may rupture.
Signs and tests
Hepatic hemangioma is usually not found until medical pictures are taken of the liver for some other reason. If the hemangioma ruptures, the only sign may be an enlarged liver.
Babies with benign infantile hemangioendothelioma may have:
