摘　　要：目的:探讨肾嗜酸细胞瘤(renal oncocytoma,RO)的临床、影像及病理特点,加深对RO的认识,提高诊疗水平。方法:回顾性分析解放军联勤保障部队第九七〇医院2021年1—3月收治的术前误诊为肾癌患者2例的影像、病理资料,复习文献并进行讨论。结果:2例患者肿瘤均位于左肾,肿瘤长径分别为2.7 cm和3.2 cm,分别行后腹腔镜左肾部分切除术和后腹腔镜左肾根治性切除术,术后病理结果证实为RO。结论:RO是一种少见的肾良性肿瘤,术前诊断困难,增强CT有一定的鉴别意义,确诊有赖于病理结果。Objective To investigate the clinical,imaging,and pathological characteristics of renal oncocytoma,and to improve the understanding,diagnosis,and treatment of renal oncocytoma.Methods The imaging and pathological data of two patients misdiagnosed with renal cell carcinoma in the 970 Hospital of PLA Joint Logistics Support Force from January to March 2021 were retrospectively analyzed.The relevant literature was reviewed and discussed.Results The tumors were located in the left kidney of two patients,with diameters of 2.7 cm and 3.2 cm respectively.The patients underwent retroperitoneal laparoscopic removal of partial left kidney and retroperitoneal laparoscopic removal of the whole left kidney separately.The pathological results confirmed the diagnosis of renal oncocytoma.Conclusion Renal oncocytoma is a rare benign renal cell tumor which is difficult to be diagnosed before surgery.Contrast-enhanced CT can provide evidence for the identification of renal oncocytoma.Its final diagnosis depends on pathological results.
