Abstract：
Xanthogranulomatous pyelonephritis may, rarely, occur as a renal cystic mass. We report a case report of a 50-year-old with a history of medically treated renal lithiasis, who consults for left low back pain. Imaging findings concluded to a Bosniak type-3 hemorrhagic cystic mass of the left kidney. The diagnosis of xanthogranumolatous pyelonephritis on its focal form was made histologically. The diagnosis of xanthogranulomatous pyelonephritis is often difficult even with surgical findings and frequently a histological surprise. This points out the importance of identifying it in pre-operative staging; the diagnosis may be suggested by the association of chronic pyelonephritis, renal stones and hypovascular renal tumor syndrome without specificity at sonography and CT.
摘要：
黄色肉芽肿性肾盂肾炎可能，很少,发生为肾脏囊性肿块。我们报告了一例50岁的病例报告，有药物治疗的肾结石病史，为左下腰痛提供咨询.影像学检查结果得出的结论是左肾的Bosniak3型出血性囊性肿块。组织学上诊断为黄色颗粒性肾盂肾炎的病灶形式。即使有手术发现，黄色肉芽肿性肾盂肾炎的诊断通常也很困难，并且经常是组织学上的意外。这指出了在术前分期中识别它的重要性；诊断可能与慢性肾盂肾炎有关。肾结石和低血管肾肿瘤综合征在超声和CT检查无特异性。
