title: [Renal inflammatory pseudotumor manifesting as a prolonged fever].
abstract: BACKGROUND
  Inflammatory pseudo-tumors (IPT) are benign neoplasms associated with local or general manifestations. Renal localization seems exceptional, and no case of fever of unknown origin caused by renal inflammatory pseudo-tumors have been reported.
  
  
  METHODS
  The authors report the case of a man presenting fever of unknown origin and inflammatory syndrome. Computerized tomography showed a renal mass. Nephrectomy was performed, and renal inflammatory pseudo-tumor was diagnosed. After surgical exeresis, the clinical and biological abnormalities vanished.
  
  
  CONCLUSIONS
  This rare diagnosis must be considered in these situations. The outcome is excellent.
