Xanthogranulomatous pyelonephritis in childhood: report on an unusual case.

ABSTRACT

A case of localised xanthogranulomatous pyelonephritis (XPN) in a 4-year-old female with an unusual radiological picture is reported. The young girl was suspected to have a liver tumour because of a hypervascularised area found by arteriography in the hepato-diaphragmatic region. Laparotomy disclosed a large mass in the upper pole of the right kidney which was adherent to the liver and to the diaphragm. Excision of the large mass including upper pole of the kidney was carried out. Recovery was uneventful. Pathological examination revealed the XPN disease pattern.
