摘要目的 探讨肾脏混合性上皮间质肿瘤(MESTK)与囊性肾瘤(CN)的多期螺旋CT表现特点,以期提高术前诊断及鉴别诊断的准确性.方法 采用盲法回顾性对比分析经手术病理证实的6例MESTK和6例CN患者的螺旋CT表现,并与病理结果进行对照.结果 MESTK和CN均表现为肾脏内单发的边缘规则多囊性肿块.其中MESTK Bosniak Ⅲ型5例,Bosniak Ⅳ型1例;6例CN均为Bosniak Ⅱ型.6例MESTK均为囊实性肿物,肿瘤内均可见数量不等的实性成分,间隔平均厚度为0.93 cm,而6例CN均表现为完全囊性病变,囊壁未见实性成分,间隔平均厚度为0.23 cm.增强扫描,MESTK的实性部分和CN的囊壁均表现为轻度或中度延迟强化.结论 多期螺旋CT扫描可为MESTK和CN的诊断提供客观依据.肿瘤有无实性成分是鉴别两者的重要CT征象. Objective To investigate the features of the mixed epithelial and stromal tumor of kidney (MESTK) and cystic nephroma (CN) on multi-detector CT (MDCT), in order to improve the accuracy of preoperative diagnosis and differential diagnosis. Methods Based on blind-retrospective review, CT features of 6 MESTK patients and 6 CN patients were reviewed retrospectively, and compared with pathological results postoperatively. Results All the lesions were single regular multi-cystic masses. Five patients with MESTK were diagnosed as Bosniak Ⅲ and 1 as Bosniak Ⅳ. In contrast, 6 of CN were all diagnosed as Bosniak Ⅱ. Six MESTK lesions were all consisted of irregular mixture of solid and cystic components, and the average thickness of septa was 0.93 cm. Six CN lesions were entirely cystic masses without solid components, and the average thickness of septa was 0.23 cm. After contrast enhancement, the solid components of MESTK and the cystic wall of CN presented mild-to-moderate delayed enhancement. Conclusion Some signs on multi-detector CT can help to differentiate MESTK and CN, especially the presence of solid components of the tumor.
