Pyogenic liver abscess in children
Common bacterial causes in children:
• S.aureus
• Strep spp
• Enteric gram negative organisms (E.coli, Klebsiella, Enterobacter, Salmonella) or Pseudomonas
Sources of infection:
• Direct extension from contiguous focus of infection (cholecystitis, subphrenic abscess, perinephric abscess)
• Biliary tree (cholangitis)
• Hematogenous spread through:
- Hepatic artery (e.g., endocarditis)
- Portal vein (from sources within abdominal cavity)
• Traumatic injury, particularly in patients managed operatively and in those with concurrent injury to hollow viscus
