Pyogenic liver abscess

Definition

Pyogenic liver abscess is a pus-filled pocket of fluid within the liver. Pyogenic means with pus.

Causes

There are many possible causes of pyogenic 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

Symptoms of liver abscess may include:

• Pain in the right upper abdomen (more common) or throughout the abdomen (less common)

• Clay-colored stools

• Dark urine

• Fever, chills, night sweats

• Loss of appetite

• Nausea, vomiting

• Unintentional weight loss

• Weakness

• Yellow skin (jaundice)

• Right shoulder pain (referred pain)

• Chest pain (lower right)

Exams and Tests

Tests may include:

• Abdominal CT scan

• Abdominal ultrasound

• Blood culture for bacteria

• Complete blood count (CBC)

• Liver biopsy

• Aspiration of abscess

• Liver function tests

Treatment

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.

Outlook (Prognosis)

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

Possible Complications

Life-threatening sepsis can develop. Sepsis is an illness in which the body has a severe inflammatory response to bacteria or other germs.

When to Contact a Medical Professional

Contact your health care provider if you have:

• Any symptoms of this disorder

• Severe abdominal pain

• Confusion or decreased consciousness

• High fever that doesn't go away

• Other new symptoms during or after treatment

Prevention

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