Experts believe that hemangiomas, a type of benign liver lesion, occurs due to hormonal changes mostly in women, states the California Pacific Medical Center. These lesions generally don't require treatment. Adenomas can be caused by oral contraceptives. An adenoma that pushes on the abdomen can cause pain, nausea and vomiting. If it gets large enough, it can bleed and even become cancerous. Focal fatty change lesions appear as fatty deposits and usually occur due to diabetes, malnutrition, hepatitis C or obesity. Although some might be cancerous, they usually do not require treatment.

Polycystic liver disease is believed to be genetic, an inherited condition that causes lesions on the liver, says the California Pacific Medical Center. The cysts do not require treatment if they are small enough, but may require marsupialization. During marsupialization, the cysts are opened and drained. A liver or kidney transplant can be necessary to treat severe cases of polycystic liver disease. Pyogenic liver abscesses, hydatid cysts and amebic liver abscesses are caused by infections, bacteria, amoebas or parasites.
