MRI AND CT FEATURES IN 2 UNUSUAL CASES OF XANTHOGRANULOMATOUS PYELONEPHRITIS

Two unusual cases of xanthogranulomatous pyelonephritis studied by bot h magnetic resonance imaging and computed tomography, are presented. E xtension of the disease depicted by both computed tomography and magne tic resonance imaging was compatible with the findings at surgery. Com puted tomography seems to be sufficient for xanthogranulomatous pyelon ephritis imaging evaluation, while magnetic resonance imaging is not r ecommended on a routine basis, since no additional valuable informatio n is yielded.
