A pyogenic liver abscess is a type of liver abscess caused by bacteria.

Signs and symptoms[edit]

Acute abscess[edit]

Chronic abscess[edit]

  • Fever
  • Abdominal discomfort
  • Enlarged liver


  • Biliary disease (most common)

E.g.: stones, cholangiocarcinoma

  • Colonic disease

E.g.: diverticulitis, appendicitis, Crohn's disease

E.g.: penetrating injury, iatrogenic (radiofrequency ablation)

Common bacterial causes[edit]


To differentiate pyogenic liver abscess from amoebic liver abscess, several features such as subjects with age more than 50 years with lungs involvement, multiple liver abscesses, with amoebic serologic titres less than 1:256 can help to pin down the diagnosis of pyogenic liver abscess.[1]

  2. Percutaneous drainage under USG or CT control
  3. Laparotomy in intra-abdominal disease
