Liver hemangioma

Overview

A liver hemangioma (he-man-jee-O-muh) is a noncancerous (benign) mass in the liver made up of a tangle of blood vessels. Also known as hepatic hemangiomas or cavernous hemangiomas, these liver masses are common and are estimated to occur in up to 20% of the population.

Most cases of liver hemangiomas are discovered during an imaging study done for some other condition. People who have a liver hemangioma rarely experience signs and symptoms and typically don't need treatment.

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