A liver hemangioma (he-man-jee-O-muh) is a noncancerous mass in the liver made up of a tangle of blood vessels. Liver hemangiomas are sometimes called hepatic hemangiomas or cavernous hemangiomas.
Most liver hemangiomas are found during a test done for another condition. These liver masses are common. Around 20% of the population is thought to have them. People who have a liver hemangioma rarely have symptoms and typically don't need treatment.
It may worry you to know that you have a mass in your liver, even if it's not cancerous. However, there's no evidence that an untreated liver hemangioma can lead to liver cancer.
In most cases, a liver hemangioma doesn't cause any symptoms. When it does cause symptoms, they may include:
However, these symptoms are typically due to something else.
Make an appointment with your healthcare team if you have any ongoing symptoms that worry you.
It's not clear what causes a liver hemangioma to form. Healthcare professionals believe that liver hemangiomas are present at birth, also known as congenital.
A liver hemangioma usually grows as a single collection of tangled blood vessels and is typically less than about 1.5 inches (about 4 centimeters) wide. Sometimes liver hemangiomas can be larger or happen in multiples. Large hemangiomas can grow in young children, but this is rare.
In most people, liver hemangiomas do not grow or cause any symptoms. But in a small number of people, liver hemangiomas grow to cause symptoms and require treatment. It's not clear why this happens.
Factors that can increase the risk of a liver hemangioma include:
Women who have been diagnosed with liver hemangiomas have a higher risk of complications if they become pregnant. The hormone estrogen, which increases during pregnancy, is believed to cause some liver hemangiomas to grow larger.
Very rarely, a growing hemangioma can cause symptoms that may require treatment. Symptoms may include pain in the upper right corner of the belly area, stomach bloating or nausea. Having a liver hemangioma doesn't mean you can't become pregnant. However, talking about the possible complications with your healthcare team can help you make a more informed choice.
Tests used to diagnose liver hemangiomas include:
Other tests may be used depending on your situation.
If your liver hemangioma is small and doesn't cause any symptoms, you likely won't need treatment. In most people, liver hemangiomas do not grow or cause symptoms. You may be scheduled for occasional follow-up exams to see if your liver hemangioma is growing.
Liver hemangioma treatment depends on the location and size of the hemangioma, whether you have more than one hemangioma, your overall health, and your preferences.
Treatment options may include:
Most liver hemangiomas are discovered during a test or procedure for something else. If your care team thinks you have a liver mass, you may be referred to a doctor who specializes in the digestive system, called a gastroenterologist, or one who specializes in the liver, called a hepatologist.
