Abstract
Acute appendicitis in pediatrics presented in scholar and adolescent ages have as its main complication an intraabdominal abscess. Moreover, acute lobar nephronia is a localized infection in the renal parenchyma. There are no cases reported about nephronia as a consequence of acute non-perforated appendicitis. This case describes a preadolescent presenting abdominal pain, vomit and fever, six days after acute appendicitis. She was admitted with signs of systemic inflammatory response syndrome, so antibiotic therapy was started. After three days there was no clinical improvement, whereby an abdominal ultrasound was performed, which reported injury in the right kidney suggestive of acute lobar nephronia and an hepatic abscess of VI and VII segments. Broad spectrum of antibiotic therapy was started with adequate clinic response. Acute lobar nephronia should be considered when studying acute appendicitis complications, given it’s aggressive behavior, accelerated progression to sepsis and frequent association with renal scarring.
