Appendicitis with direct fistulation into the liver: a forgotten cause of pyogenic liver abscess

Hepatic Abscess Following Acute Appendicitis

The authors present the case of a 29-year-old female diagnosed with acute appendicitis who underwent an uneventful laparoscopic appendectomy. Three weeks later, she returned to the emergency department with fevers, abdominal pain, chills, and nausea. Laboratory analysis revealed elevated liver enzymes and leukocytosis, and a computed tomography scan of the abdomen revealed a liver abscess. Interventional radiology placed an 8 French drainage catheter in the hepatic abscess and drained 40cc of purulent fluid. A culture of the abscess fluid revealed Streptococcus constellatus, Bacteroides fragilis, and Bacteroides ovatus. We believe appendicitis causes hematogenous spreading of bowel organisms along the portal vein, which is seeded to the liver.
