Pyogenic liver abscess
Liver abscess; Bacterial liver abscess; Hepatic abscess
Pyogenic liver abscess is a pus-filled pocket of fluid within the liver. Pyogenic means "with pus".
There are many possible causes of liver abscesses, including:
- Abdominal infection, such as appendicitis, diverticulitis, or a perforated bowel
- Infection in the blood
- Infection of the tubes draining bile (bile ducts)
- Recent endoscopy of the bile draining tubes
- Trauma that damages the liver
A number of common bacteria may cause liver abscesses. In most cases, more than one type of bacteria are found.
Symptoms of liver abscess may include:
Exams and Tests
Treatment usually consists of placing a tube through the skin into the liver to drain the abscess. Less often, surgery is needed. You will also receive antibiotics for about 4 to 6 weeks. Sometimes, antibiotics alone can cure the infection.
This condition can be life threatening. The risk for death is higher in people who have many liver abscesses.
Life-threatening sepsis can develop. Sepsis is an illness in which the body has a severe inflammatory response to bacteria or other germs.

Prompt treatment of abdominal and other infections may reduce the risk of developing a liver abscess, but most cases are not preventable.
