Symptoms:

Some 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.

Babies with benign infantile hemangioendothelioma may have:

• A growth in the abdomen
• Anemia
• Signs of heart failure

The following tests may be performed:

• Blood tests
• CT scan of the liver
• Hepatic angiogram
• MRI
• Single-photon emission computed tomography (SPECT)
• Ultrasound of the abdomen
