Hepatic cysts, or liver cysts, are estimated to occur in about 5 percent of the American population, according to PubMed. They are more common in women than in men, especially as people age.
Liver cysts are abnormal fluid-filled sacs in the liver that can either be present at birth or develop later in life. Most cysts do not cause symptoms or require treatment, according to the American Liver Foundation.
On the rare occasion that cysts do cause symptoms, treatment options include drainage or surgical removal, according to Mayo Clinic. Surgical laparoscopy is the method of treatment for simple cysts that require drainage, explains PubMed Central.
