Abstract:
Xanthogranulomatous pyelonephritis is an uncommon chronic renal infection, which is usually found on middle-aged women and is rare in infant. Sometimes it forms focal mass like lesion of kidney with pathologically characteristic lipid-laden macrophage. A 1-month female infant was admitted for fever and moaning sound. On work-up of urinary tract infection, abdomen ultrasonography and computed tomography revealed a large mass on the upper portion of right kidney and PET/CT showed homogeneously increased 18F-FDG uptake. The radical nephrectomy of right kidney was performed and histology revealed a focal xanthogranulomatous pyelonephritis. To our knowledge, this is the first report presenting the finding of 18F-FDG PET/CT in the childhood xanthogranulomatous pyelonephritis.
