【摘要】 目的:分析多房囊性肾癌的影像学表现,以提高对此病的认识及正确诊断率。方法:回顾性的分析病理证实的9例多房囊性肾癌患者的CT/MRI图像,其中1例患者为双侧多房囊性肾癌。结果:10个病灶,均边界清楚。8个病灶囊壁局部增厚,2个囊壁菲薄。3个病灶间隔菲薄,4个间隔增厚不均匀,3个间隔增厚并有结节。增强扫描囊壁及分隔均不同程度强化。2个病灶见囊壁和/或间隔钙化。Bosniak分级ⅡF级3个,Ⅲ级7个。结论:多房囊性肾癌多表现为多房囊性肿物,边界清楚,囊壁可有局部增厚,间隔粗细不均,附壁及间隔结节直径小于5mm。需要与肾囊肿及肾癌囊性变鉴别,表现典型者可作出正确诊断。更多还原

【Abstract】 Objective:To explore the imaging features of multilocular cystic renal cell carcinoma,(MCRCC) and to evaluate its clinical value.Methods:The CT and MRI findings of MCRCC in 9 patients proved by operation and pathology were retrospectively reviewed,one of the patients had bilateral MCRCC.Results:10 tumors all appeared as well-defined multilocular cystic mass with thin coarse septum in 3 cases,irregular thickening septum in 4 cases and septum with nodule in 3 cases.The cystic wall presented with irregular thickening in 8 cases,2 cases with thin cystic wall.Various degrees of cystic wall and septum enhancment were detected after intravenous administration of contrast material.Calcification of cystic wall and/or septum were found in 2 cases.3 of 10 tumors were classified as Bosniak classification category ⅡF and the others were classified as category Ⅲ.Conclusion:On CT and MRI images,MCRCC appeared as a well-defined multilocular cystic mass with irregular thickening cystic wall and/or septum,lacking an expansile nodule larger than 5 mm.MCRCC must be differentiated from renal cyst and necrotic cystic renal cell carcinoma(NCRCC).We could get definite diagnosis with that typical features.更多还原
