title: [Xanthogranulomatous pyelonephritis].
abstract: An 11-year-old boy suffered from malaise, weight loss and pallor. A palpable abdominal tumor on the right side, anemia and increased C-reactive protein were detected. Intravenous urography revealed destruction of the right kidney resembling Wilms tumor. But ultrasound and computered tomography rised skepticism. Analysis of previously documented cases suggests that xanthogranulomatous pyelonephritis must equally be considered in a child with unilaterally enlarged kidney without function, especially when the child shows fever, leukocytosis, bacteriuria, anemia, leukocyturia, calculi of the urinary tract, abdominal pain and/or a palpable abdominal tumor. Ultrasound and computered tomography can lead to the diagnosis, and identify extrarenal infiltration. Nephrectomy results in complete cure and is therefore the treatment of choice.
