title: [Pseudotumoral xanthogranulomatous pyelonephritis. Apropos of a case].
abstract: Xanthogranulomatous pyelonephritis may, rarely, occur as a renal tumour syndrome (simulating mainly a renal cell carcinoma). We report one case. The diagnosis is often difficult (even with surgical findings) and frequently a histological surprise. This points out the importance of identifying it in preoperative staging; the diagnosis may be suggested by the association of chronic pyelonephritis, renal stones and hypovascular renal tumour syndrome without specificity at sonography and CT.
