摘　　要：目的 探讨肾脏混合型上皮和间质肿瘤的影像学表现,提高对该病的认识。方法 回顾性分析7例经病理证实的肾脏混合型上皮和间质肿瘤患者的CT及MRI影像学特征。结果 7例患者共有8个病灶,3个病灶为以囊性为主囊实性占位,表现为细小分隔,伴或不伴条片状实性成分或壁结节,T_2WI壁结节呈稍低信号;3个病灶为以实性为主囊实性占位,病变内多发微囊、小囊结构,T_2WI实性成分信号混杂,部分呈稍低信号,DWI呈稍低信号;2个病灶为实性结节或肿块,较大者内见少许脂肪成分。结论 肾脏混合型上皮和间质肿瘤影像学表现有一定的特征性,有助于术前诊断及鉴别诊断以选择更合适的手术方案。Objective To investigate the CT and MRI findings of mixed epithelial and stromal tumor of the kidney(MESTK) in order to improve the understanding of the disease. Methods The CT and MRI features of 7 patients with MESTK confirmed by pathology were analyzed retrospectively. Results There were a total of 8 lesions in 7 patients.3 lesions were cystic and solid masses with more cystic components;The lesions were multicystic structures with or without wall nodules which showed hypointense on T_2WI;3 lesions were cystic and solid masses with more solid components which showed hypointense on T_2WI partly and DWI;The lesion were multiple microcapsules and small cystic structures;2 lesions showed solid lesions with a small amount of fat in the larger one. Conclusion There were some imaging characteristics of MESTK which were helpful for preoperative diagnosis, differential diagnosis and selecting a more suitable surgical plan.
