摘　　要：目的分析多房囊性肾细胞癌(MCRCC)及肾细胞癌囊性变(NCRCC)的CT特征,提高对二者鉴别能力。方法回顾性分析经手术病理证实的11例MCRCC和16例NCRCC的CT特征。结果 81.8%(9/11)的MCRCC分布在BosniakⅡF、Ⅲ级,6 2.5%(1 0/1 6)的N C R C C主要分布在BosniakⅣ级。MCRCC与NCRCC囊壁形态存在差异(P<0.05)。MCRCC均呈多房性改变,NCRCC仅37.5%(6/16)呈多房性改变。72.7%(8/11)MCRCC的囊液CT值≤20HU,81.3%(13/16)的NCRCC囊液CT值>20HU。MCRCC与NCRCC病灶内软组织结节大小存在明显差异(P=0.003)。结论MCRCC与NCRCC的CT表现具有一定特征性,综合分析可提高对两者的鉴别。Objective Objective To analyze CT characteristics of multilocular cystic renal cell carcinoma（MCRCC） and necrotic cystic renal cell carcinoma（NCRCC）,so as to improve the discrimination between both of them. Methods Methods CT characteristics of 11 cases of MCRCC and 16 cases of NCRCC which proved by surgery and pathology were analyzed retrospectively. Results 81.8%（9/11） of MCRCC belonged to Bosniak classification II F and III,while 62.5%（10/16） of NCRCC was mostly Bosniak classification Ⅳ.MCRCC and NCRCC differed from each other in morphology of cyst wall（P〈0.05）.All MCRCC presented mulltilocular changes, and merely 37.5%（6/16） had such changes.The CT value of cystic fluid lower than 20 HU for 72.7%（8/11） of MCRCC,and was higher than 20 HU for 81.3%（13/16） of NCRCC.There was significant difference in size of intralesional soft-tissue nodules between MCRCC and NCRCC（P=0.003）. Conclusion The CT manifestation of MCRCC and NCRCC was somewhat characteristic,and it was found to better discriminate them after comprehensive analysis.
