title: Focal xanthogranulomatous pyelonephritis: diagnostic and therapeutic aspects.
abstract: The authors report 2 cases of localized xanthogranulomatous pyelonephritis (XGP) in which computed tomography (CT) permitted to raise a motivated clinical suspicion of inflammatory disease: the surgical exploration documented absence of neoplasm and allowed a conservative therapy implying only the removal of the mass. A literature review confirms that some CT signs in XGP permit differentiation from carcinoma. If they are present, in unifocal cases of disease, the authors suggest a limited surgical approach and a therapeutic strategy as conservative as possible.
