Overview

A liver hemangioma (he-man-jee-O-muh) is a noncancerous (benign) mass in the liver. A liver hemangioma is made up of a tangle of blood vessels. Other terms for a liver hemangioma are hepatic hemangioma and cavernous hemangioma.

Most cases of liver hemangiomas are discovered during a test or procedure for some other condition. People who have a liver hemangioma rarely experience signs and symptoms and don't need treatment.

It may be unsettling to know you have a mass in your liver, even if it's a benign mass. There's no evidence that an untreated liver hemangioma can lead to liver cancer.
