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 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.
