目的:分析囊性肾癌的CT和MRI表现,旨在提高术前正确诊断率。方法:回顾性分析经手术病理证实的16例囊性肾癌的CT和MRI表现。结果:囊性肾癌16例,囊壁不规则增厚12例,间隔不规则增厚8例,囊壁结节10例;囊性病变内出现异常软组织影6例,和/或囊性病变周围肾实质内出现异常软组织影4例;钙化2例;增强扫描实性部分明显增强8例,中度增强5例,轻度增强3例。结论:囊性肾癌的CT、MR表现有一定特征,表现典型者可做出诊断。
Objective： To analyze the CT and MRI features of cystic carcinoma of kidney. Methods： The CT and MRI findings of cystic carcinoma of kidney in 16 patients proved by operation and pathology were retruspectively reviewed. Results： Of the 16 patients, the CT and MR findings of tumors were irregular thickening of the cystic wall in 12 eases, and septa were irregular thickening in 8 cases, and nodules in the cystic wall were detected in 10 cases ; abnorma/density or signal intensity soft tissues component inside the cyst were present in 6 cases, and/or the changes around the cyst were present in 4 cases, calcification was found in 2 cases; substance component enhaneement after contrast administration were detected,with obvious enhancement in 8 cases, moderate enhancement in 5 cases, slight enhancement in 3 cases. Conclusion： The CT and MRI findings of cystic carcinoma of kidney have their own characteristics. We could get definite diagnosis with that typical features.
