Ultrasound images of Xanthogranulomatous pyelonephritis pediatric

Ultrasound images of Xanthogranulomatous pyelonephritis results from chronic infection in an obstructed kidney and children present with a history of general malaise, lowgrade fever and flank pain and may be found to be anaemic. The finding of a palpable abdominal mass on examination often leads to an early diagnosis of a possible Wilms’ tumour. On sonography the kidney is diffusely enlarged, with loss of the normal corticomedullary differentiation. The presence of calyceal dilatation with debris and calculi in the collecting system and confirmation of urinary infection in addition to the generalized involvement of the kidney helps to differentiate this condition from Wilms’ tumour (Fig.ultrasound images below) Occasionally CT scanning may also be helpful. The kidney will usually be found to be non-functioning on a DMSA scan and nephrectomy is required.
