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

Signs and symptoms

Acute abscess

Chronic abscess


E.g.: stones, cholangiocarcinoma

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

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

Common bacterial causes


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
