摘要
目的:提高对囊性肾癌CT表现的认识。材料与方法:回顾分析了21例经手术病理证实的囊性肾癌的CT平扫及强化的影像资料。结果:21例中,肿瘤大小2.1cm-13.4cm不等,形态圆形或卵圆形,肿瘤边缘光滑11例,不光滑10例。与周围肾脏分界清楚5例,不清楚16例。9例单房,12例多房,囊壁厚薄不均,11例见壁结节,6例见钙化,囊内容物呈水样或稍高密度,密度不均,CT值为4.0-42.3Hu。增强检查,肿瘤实性成分均有不同程度的强化。结论:囊性肾癌在CT平扫及多期增强扫描中仍有一定的特征性表现,对临床的治疗具有重要的指导意义。
Purpose： to improve the recognition of CT in cystic renal cell carcinoma. Materials and Methods： 21 cases of cystic renal cell carcinoma confirmed by operation and pathology were retrospectively analyzed. Results： in 21 cases, the tumor size 2. lcm - 13. lcm ranging, round or oval shape, the tumor edge smooth in 11 cases, not smooth in 10 cases. 5 cases were clearly associated with the surrounding kidney, and 16 cases were not clear. 9 cases of simple, 12 cases of muhilocular and capsule wall thickness not all, 11 cases showed wall nodules, 6 cases calcification, cystic content is water or slightly high density, une,~en density, the CT value of 4. 0 -42. 3Hu. Enhanced examination, the tumor solid components have different degrees of enhancement. Conclusion ： cystic renal cell carcinoma is a characteristic manifestation of CT scan and multi phase enhancement scanning, which has important guiding significance for clinical treatment.
