Abstract

Renal Abscess (RA) is rare in pediatric population and the incidence is unknown. Unrecognized and untreated RA can be life-threatening, leading to sepsis, loss of a kidney, and even death. Initial presentation is often nonspecific which can delay diagnosis. Xanthogranulomatous Pyelonephritis (XP) is a sequela of chronic suppurative infections, seen in 0.6% to 1.0% of patients with chronic pyelonephritis, where part of the kidney (focal, most common in children) or the entire kidney becomes a suppurative inflammatory and necrotic mass. This case is atypical: A longstanding subclinical urinary tract infection (given the history of dysuria and low-grade fever) eventually led to the formation of an abscess in the spectrum of XP, triggering a systemic inflammatory response syndrome that closely resembled the B symptoms of malignancy.
