Peritonitis due to Staphylococcus Aureus: An Unusual Complication of Pediatric Renal Abscess

Staphylococcus aureus causes intra-abdominal infections primarily due to hematogenous seeding. Abscesses in retroperitoneal organs, and specifically renal abscesses are rare complications of staphylococcal bacteremia in children as compared to osteomyelitis, or septic arthritis. We report a case of a ruptured staphylococcal renal abscess in a child without renal anomalies that presented as clinical peritonitis in order to underscore this potentially elusive diagnosis.
