Xantogranulomatous pyeloneprhritis in children

Area of Science:

• Pediatric Nephrology
• Renal Pathology
• Medical Imaging

Background:

• Xanthogranulomatous pyelonephritis (XPN) is a rare, severe chronic kidney inflammation.
• Characterized by renal parenchyma destruction, giant cells, lipid-laden macrophages, and fibrosis.
• Pathomechanism is poorly understood, often associated with urinary tract obstruction and infection.

Purpose of the Study:

• To review and illustrate the clinical, radiological, surgical, and pathological characteristics of XPN in children.
• To highlight XPN's presentation and diagnostic challenges in pediatric patients.
• To emphasize the importance of histopathological confirmation.

Main Methods:

• Review of surgically and histopathologically proven cases of XPN in children.
• Analysis of clinical manifestations, radiological findings (primarily CT), and surgical outcomes.
• Correlation of imaging findings with pathological characteristics.

Main Results:

• XPN presents with non-specific symptoms and can mimic renal neoplasms.
• Computed tomography (CT) is crucial for diagnosis and differentiation from malignancy.
• Focal XPN must be considered in the differential diagnosis of pediatric renal masses.
• Definitive diagnosis relies on post-nephrectomy pathological assessment.

Conclusions:

• XPN exhibits diverse clinical presentations in children.
• CT imaging plays a pivotal role in diagnosing XPN.
• Management requires individualized consideration of conservative and surgical options.
• Histopathology is essential for confirming XPN and excluding other renal diseases.
