Noncancerous, or benign, liver tumors are common. They do not spread to other areas of the body, and they usually do not pose a serious health risk. Benign tumors are significantly less dangerous than malignant tumors. Benign tumors by themselves are not life-threatening.
Types of benign liver lesions include: Liver hemangioma, the most common benign liver lesion. It occurs in up to 5% of adults and consists of abnormal blood vessels. Focal nodular hyperplasia, which often develops in women and has a scar-like appearance. Liver adenoma, a rare liver tumor.
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.
Relatively common in the liver, benign (noncancerous) liver masses or lesions may incidentally be detected on imaging studies, abnormal liver function tests, or during investigation of abdominal pain.
A liver hemangioma is a benign (noncancerous) tumor. It’s made up of tangled blood vessels. It usually doesn’t cause symptoms, unless it’s especially large.
There are several types of benign liver tumors, including the following: Hepatocellular adenoma. This benign tumor is linked to the use of certain drugs. Most of these tumors remain undetected. Sometimes, an adenoma will rupture and bleed into the abdominal cavity, requiring surgery. Adenomas rarely become cancer. Hemangioma. This type of ...
Benign liver tumors are relatively common. Most are asymptomatic, but some cause hepatomegaly, right upper quadrant discomfort, or intraperitoneal hemorrhage. Most are detected incidentally on ultrasound or other scans (see Imaging Tests of the Liver and Gallbladder ).
Benign liver tumors are often diagnosed randomly. HHs are the most frequent lesions. The majority of benign liver tumors does not need any kind of treatment, and even follow-up is only necessary in some patients. In asymptomatic HH and FNH regardless of their size, no intervention is required.
Hepatic hemangiomas are the most common benign tumors of the liver. In a large retrospective cross-sectional study consisting of 83,181 patients who had undergone abdominal CT and/or MRI scans, the prevalence of hepatic hemangiomas was found to be 2.5% [1].
Hepatic adenomas are benign tumors that start from the main type of liver cells. Most do not cause symptoms and do not need treatment. But if they cause stomach pain, a mass in the belly, or blood loss, they may need to be removed.
