[A case of xanthogranulomatous pyelonephritis in an infant].

A case of xanthogranulomatous pyelonephritis (XPN) in a boy of 20 months is reported. The patient suffered from high fever. Leukocytoses, anaemia and enhanced C-reactive protein were detected. Ultrasound and CT showed an enlarged left kidney with atypical structures. Malignancy could not be excluded praeoperatively. The IV pyelogram and scintigraphy revealed a functioning left kidney. Nephrectomy resulted in complete cure. A short description of the XPN and a survey of the literature is given.
