肾脏混合性上皮和间质肿瘤与囊性肾癌的多层螺旋CT鉴别诊断探讨(1)
[摘要] 目的 分析腎脏混合性上皮和间质肿瘤与囊性肾癌的多层螺旋CT鉴别与诊断，减少误诊、漏诊的情况。 方法 通过盲法回顾性分析2016年11月—2018年11月在该院确诊的7例肾脏混合性上皮和间质肿瘤患者的临床资料，同时分析10例囊性肾癌患者的临床资料与表现。所有患者均行多层螺旋CT扫描检测与病理检查，并将二者结果进行比对。 结果 7例肾脏混合性上皮和间质肿瘤与8例囊性肾癌表现均发现多囊性肿块。其中，肾脏混合性上皮Bosniak Ⅲ6例，Bosniak Ⅳ型1例。8例囊性肾癌均表现为囊实性病变。行增强扫描，囊性肾癌的实性部分呈现不同程度的强化。时间越久，增强程度增加。2例囊性肾癌发现透明细胞癌囊变，均见间隔层增厚，间隔表面不光滑。行增强扫描，囊壁、壁结节呈现不同程度的增强，实质期强化减退行增强扫描。 结论 增强扫描下，MSCT与CRCC均表现不同程度的强化，但实性成分数量以及增强方式等为临床鉴别二者提供了参考。

[Abstract] Objective To analyze the multi-slice spiral CT diagnosis and diagnosis of mixed renal epithelial and stromal tumors and cystic renal cell carcinoma， and to reduce the misdiagnosis and missed diagnosis. Methods The clinical data of 7 patients with mixed renal epithelial and stromal tumors diagnosed in our hospital from November 2016 to November 2018 were retrospectively analyzed. The clinical data and performance of 10 patients with cystic renal cell carcinoma were analyzed. All patients underwent multi-slice spiral CT scan and pathological examination， and the results were compared. Results 7 cases of mixed renal epithelial and stromal tumors and 8 cases of cystic renal cell carcinoma showed polycystic masses. Among them， 6 cases of renal mixed epithelial Bosniak III and 1 case of Bosnian IV type. Eight cases of cystic renal cell carcinoma showed cystic lesions. Intensive scanning， the solid part of cystic renal cancer showed different degrees of enhancement. The longer the time， the greater the increase. 2 cases of cystic renal cell carcinoma were found to have clear cell carcinoma cystic changes， and the interstitial layer was thickened and the interstitial surface was not smooth. In the enhanced scan， the wall of the capsule and the nodules of the wall showed different degrees of enhancement， and the enhancement of the enhancement in the parenchyma was enhanced. Conclusion Under enhanced scanning， both MSCT and CRCC showed different degrees of enhancement， but the number of solid components and enhancement methods provided a reference for clinical identification.
