| Abstract |
|
Xanthogranulomatous pyelonephritis is an atypical form of severe chronic renal parenchymal
infection, which can be mistaken for tumor or other inflammatory renal disease due to similar clinical
manifestations.
This disease was classified into three stages based on the extent of involvement of renal and
adjacent tissue by the xanthogranulomatous process. In stage I (nephric), the characteristic xantho-
granulomatous inflammatory process is confined to the kidney.
The stage II lesion (perinephric) involves the renal parenchyma and Gerota’s fat, whereas the stage
III lesion (paranephric) involves the renal parenchyma and its surrounding fat, with widespread
retroperitoneal involvement.
This disease is being predisposed by urinary obstruction, inappropriatly treated chronic urosepsis,
lymphatic obstruction, abnormal immune reaction, diabetes melitus etc.
We report here the 13 year old male patient suffering from Xanthogranulomatous pyelonephritis
stage I who showed intermittent fever, left flank pain, and weight loss, which was confirmed by IVP,
Abdominal CT, renal angiography, ultrasonography, and pathologic findings. |
