Xanthogranulomatous pyelonephritis is a rare disease probably caused by long-standing obstruction and secondary infection. We report a case in a 47-year-old woman with no previous history of renal stones. Preoperative diagnostic workout included ultrasonography, CT scan, and drainage. Nephrectomy was performed, and the patient's postoperative recovery was uneventful. The difficulties of correct preoperative diagnosis are discussed.
