目的　探讨肾脏炎性假瘤声像图特征及其病理基础。方法　应用超声显像观察肾脏炎性假瘤的二维声像图特点、彩色多谱勒血流显像和超声引导穿刺活检。结果　肾脏炎性假瘤具有肾脏占位性病变的一般声像图特征和血流信号丰富等特点 ,病理为肾实质非特异性炎症。结论　超声显像仅作为肾脏炎性假瘤诊断的初步手段 ,超声引导穿刺活检应作为确诊的必要方法 Objective To investigate the characteristics and pathology of renal inflammatory pseudotumor. Methods Ultrasound imaging was used to observe the two-dimensional sonographic features of renal pseudotumor, color Doppler flow imaging and ultrasound guided biopsy. Results The renal inflammatory pseudotumor had the characteristics of general sonographic features and richness of blood flow signals in the lesions of the kidney. The pathology was non-specific inflammation of the renal parenchyma. Conclusion Ultrasound imaging is only used as a preliminary diagnosis of renal inflammatory pseudotumor, ultrasound-guided biopsy should be used as a necessary method of diagnosis
