Definition of Hepatic hemangioma
A hepatic hemangioma is a noncancerous liver made of widened (dilated) blood vessels.
Causes, incidence, and risk factors
A hepatic hemangioma is the most common noncancerous tumor of the liver. It is believed to be a birth defect.
Hemangiomas may cause bleeding or interfere with organ function, depending on their location. Most cavernous hemangiomas do not produce symptoms. In rare cases, a cavernous hemangioma may rupture.
Signs and tests
Hepatic hemangioma is usually not discovered until medical pictures are taken of the liver for some other reason. If a cavernous hemangioma ruptures, the only sign may be an enlarged liver.
Most cavernous hepatic hemangiomas are treated only if the child is in persistent pain.
