Overview
Pathophysiology
- Development of pyogenic liver abscess is the result of extension of infection through the following:[1][2][3][4]
- Portal vein
- Hepatic arteries as metastatic abscessess
- Direct spread from nearby infection
- Trauma
- Retroperitoneal extension from appendix (suppurative appendicitis most frequent source of infection)
- Ascending biliary infection is the most common source of pyogenic liver abscess
- Bacteria involved in pyogenic liver abscess include:
