摘　　要：目的 :探讨黄色肉芽肿性肾盂肾炎的影像学表现。材料和方法 :回顾性分析 5例黄色肉芽肿性肾盂肾炎 ,全部病例均行X线、B超和CT检查并经手术、病理证实 ,行MR和血管造影各 1例。结果 :X线 :肾影增大、肾结石和肾盂肾盏的形态改变。B超 :肾实质内的占位性病变、结石和肾周改变。CT :肾实质内单 /多发靠近肾盂肾盏囊实性占位 ,增强后实性部分增强 ;多合并结石 ;病变常向肾外发展 ;患肾功能受损。结论 :CT的影像学价值较X线和B超高。定性须密切结合临床 ,尿泡沫细胞有确诊意义。Purpose: To evaluate the imaging features and diagnostic value of X-ray film, US and CT in Xanthogranulomatous Pyelonephritis (XGPN). Meterials and Methods: Imaging findings of 5 patients of XGPN proved by operation and pathology were retrospectively analyzed. Results: X-ray: the enlargement of kindney shadow, distorsion of calyces and renal calculus were observed. Sonography: space occupying lession, renal calculus and extensive infilitation were seen. CT features included ① the disease appeared as a parenchymal mass which was often closed to the renal pelvis or calyce on plain scan, and enhanced after enhancement; ② Renal calcalus; ③ Extensive infilitration to the perirenal or pararenal space; ④Impairment of renal function. Conclusion: CT is superior to the plain film and US in diagnosis of XGPH. The finding of foam cells can play a significant role in clinical diagnosis of XGPN.
