摘　　要：目的 探讨肾嗜酸细胞腺瘤的CT特征,提高对该病的诊断能力。方法 收集新疆医科大学附属肿瘤医院经手术病理证实的10例肾嗜酸细胞腺瘤患者的临床资料及影像学检查,结合国内外相关研究成果及我院病例,对病变进行回顾性分析。结果 本组资料的肾嗜酸细胞腺瘤患者中,男性1人,女性9人,年龄范围在29-76岁,平均年龄是52.6岁。所有病变均为单侧单发,均来自肾皮质,6例位于右肾,4例位于左肾。7例为类圆形,3例为卵圆形;病变最大长径范围为8.00-0.70cm,平均长径为4.08cm;所有病变均无钙化,其中1例见囊变、坏死。所有病变CT平扫表现为密度不均匀,CT平扫4例表现为稍高密度,1例表现为等密度,5例表现为稍低密度。增强扫描均呈“快进慢出”的方式,1例出现假包膜,7例呈中央瘢痕且均呈延迟强化特征,2例出现阶段性强化反转。结论 当CT检查为肾皮质区出现边界清楚、密度不均匀的肿物,增强扫描呈“快进慢出”,出现中央瘢痕且延迟强化等特征时,要考虑到肾嗜酸细胞腺瘤。ObjectiveTo explore the CT features of renal eosinophilic cell adenoma and improve the diagnostic ability of this disease.MethodsThe clinical data and imaging examinations of 10 patients with renal eosinophilic cell adenoma confirmed by surgical pathology were collected from the Affiliated Cancer Hospital of Xinjiang Medical University,and the lesions were retrospectively analyzed by combining the relevant research results at home and abroad and the cases in our hospital.ResultsAmong the patients with renal eosinophilic adenoma in our data set,1 was male,9 were female,and the age range was 29-76 years old,the average age was 52.6years old. All the lesions were unilateral and from the renal cortex, 6 cases were located in the right kidney and 4 cases in the left kidney;7 cases were round and 3 cases were ovoid;the maximum diameter of the lesions ranged from 8.00-0.70 cm, and the average diameter of the lesions was 4.08 cm;all the lesions were free of calcification, and cystic degeneration and necrosis were seen in 1 case. All the lesions showed uneven density on CT scan, 4 cases showed slightly high density, 1 case showed isodensity and 5 cases showed slightly low density on CT scan. The enhancement scans all showed a“fast-in-slow-out”pattern, with one case showing a pseudo-envelope, seven cases showing a central scar with delayed enhancement, and two cases showing a reversal of the stage of enhancement.ConclusionRenal eosinophilic adenoma should be considered when there is a well-defined mass with heterogeneous density in the renal cortical area on CT examination, and the enhancement scan shows the features of“fast-in-slow-out”, central scar and delayed enhancement.
