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.
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.
This rare diagnosis must be considered in these situations. The outcome is excellent.
炎性假瘤（IPT）是与局部或全身表现相关的良性肿瘤。肾脏定位似乎较为罕见，且尚无由肾脏炎性假瘤引起不明原因发热的病例报道。
作者报告了一例出现不明原因发热和炎症综合征的男性病例。计算机断层扫描显示肾脏有肿块。进行了肾切除术，诊断为肾脏炎性假瘤。手术切除后，临床和生物学异常消失。
在这些情况下必须考虑这种罕见的诊断。预后良好。
