Liver abscess Liver abscess on axial CT image: a hypodense lesion in the liver with peripherally enhancement. Specialty Gastroenterology
A liver abscess is a mass filled with pus inside the liver .[1] Common causes are abdominal conditions such as appendicitis or diverticulitis due to haematogenous spread through the portal vein .[2] It can also develop as a complication of a liver injury .
Causes
Risk factors for developing liver abscess can be due to infection , post-procedural infection and metastasis such as primary liver tumours , liver metastasis , biliary procedures, biliary injuries, biliary tract disease, appendicitis , and diverticulitis .[3]
Major bacterial causes of liver abscess include the following:[4]
However, as noted above, many cases are polymicrobial.
Diagnosis
Types
A large pyogenic liver abscess presumed to be the result of appendicitis
There are several major forms of liver abscess, classified by cause:[3]
Pyogenic liver abscess , which is most often polymicrobial, accounts for 80% of hepatic abscess cases in the United States.
Amoebic liver abscess due to Entamoeba histolytica accounts for 10% of cases. The incidence is much higher in developing countries.
Fungal abscess, most often due to Candida species, accounts for less than 10% of cases.
Iatrogenic abscess, caused by medical interventions
Management
Draining of the abscess and antibiotics: IV metronidazole and third generation cephalosporin /quinolones , β-lactam antibiotics , and aminoglycosides are effective.[3]
Prognosis
The prognosis has improved for liver abscesses. The mortality rate in-hospital is about 2.5-19%. The elderly , ICU admissions, shock , cancer , fungal infections , cirrhosis , chronic kidney disease , acute respiratory failure , severe disease, or disease of biliary origin have a worse prognosis .[5]
