Liver cysts: A cause of stomach pain?

Date Updated: 02/16/2022

Answer Section

Simple liver cysts are fluid-filled cavities in the liver. Usually, they cause no signs or symptoms and need no treatment. However, they may become large enough to cause pain or discomfort in the upper right part of the abdomen.

Most liver cysts can be detected on ultrasound or computerized tomography (CT) scans. When needed, treatment may include drainage or removal of the cyst.

The cause of simple liver cysts isn't known. They may be the result of a malformation present at birth. Rarely, liver cysts may indicate a serious, underlying condition such as:

Polycystic liver disease, an inherited disorder
Echinococcus infection, a parasitic infection
Liver cancer
