Liver abscess; Bacterial liver abscess

Pyogenic liver abscess is a pus-filled area in the liver.

I Would Like to Learn About:

  • Causes

    There are many potential causes of liver abscesses, including:

    • Abdominal infection such as appendicitis, diverticulitis, or a perforated bowel
    • Infection in the blood
    • Infection of the bile draining tubes
    • Recent endoscopy of the bile draining tubes
    • Trauma that damages the liver

    The most common bacteria that cause liver abscesses are:

    • Bacteroides
    • Enterococcus
    • Escherichia coli
    • Klebsiella pneumoniae
    • Staphylococcus aureus
    • Streptococcus

    In most cases, more than one type of bacteria is found.

  • Symptoms

    • Chest pain (lower right)
    • Clay-colored stools
    • Dark urine
    • Fever, chills
    • Loss of appetite
    • Nausea, vomiting
    • Pain in right upper abdomen (more common) or throughout the abdomen (less common)
    • Unintentional weight loss
    • Weakness
    • Yellow skin (jaundice)
  • Exams and Tests

    Tests may include:

    • Abdominal CT scan
    • Abdominal ultrasound
    • Bilirubin blood test
    • Blood culture for bacteria
    • Complete blood count (CBC)
    • Liver biopsy
    • Liver function tests
  • Treatment

    Treatment usually consists of placing a tube through the skin to drain the abscess. Less often, surgery is required. You will also receive antibiotics for about 4 - 6 weeks. Sometimes, antibiotics alone can cure the infection.

  • Outlook (Prognosis)

    This condition can be life threatening some patients. The risk for death is higher in people who have many liver abscesses.

  • Possible Complications

    Life-threatening sepsis can develop.

  • When to Contact a Medical Professional

    Call your health care provider if you have:

    • Any symptoms of this disorder
    • Severe abdominal pain
    • Confusion or decreased consciousness
    • Persistent high fever
    • Other new symptoms during or after treatment
  • Prevention

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