Overview

Hemangioma is a noncancerous mass in the liver. They are made up of a tangle of blood vessels. Liver hemangiomas also are known as hepatic or cavernous hemangiomas.

Symptoms

Hemangiomas rarely cause symptoms. When they do, symptoms may include:

• Pain in the upper right abdomen.
• Feeling full after eating only a small portion of food.
• Nausea.
• Vomiting.

There's no evidence that this kind of noncancerous mass can lead to liver cancer.

Treatments

Most masses don't need treatment. If a mass becomes large and presses on other structures in the abdomen, surgery might be needed.
