title: [A case of xanthogranulomatous pyelonephritis presenting with the flank subcutaneous mass].
abstract: A 51-year-old female exhibited fever, left flank pain and left flank mass in March, 1993. Drip infusion pyelography (DIP) revealed a non-functioning left kidney with shadows of calculi, and abdominal computerized tomography (CT) showed renal calculi and multilocular cystic lesions in the left kidney extending through the perinephric space into the mass on the left flank. Percutaneous nephrostomy and percutaneous drainage were performed, followed by left nephrectomy. Histopathological findings revealed xanthogranulomatous pyelonephritis. There have been a few case reports of xanthogranulomatous pyelonephritis forming nephrocutaneous fistula in the back.
