目的探讨囊性肾细胞癌的CT影像特征,旨在提高其诊断与鉴别诊断水平。方法回顾性分析13例经手术病理证实的囊性肾细胞癌的CT表现特征。结果 8例囊性肾癌其囊液呈水样密度,5例囊液密度增高,不均匀;6例伴位置不同、程度不一的斑点状钙化;10例囊壁增厚或厚薄不均,4例伴囊内厚薄不均分隔,5例伴大小不一的软组织结节;增强扫描10例囊壁及间隔软组织轻中度强化,3例肿瘤实性成分明显强化。结论 CT对囊性肾细胞癌的诊断和鉴别诊断具有一定的临床实用价值。
Objective To explore the features of CT images of cystic renal cell carcinoma in order to improve its diagnostic and differential diagnosis. Methods The CT features of 13 cases of cystic renal cell carcinoma confirmed by surgery and pathology were retrospectively analyzed. Results The cyst fluid density of 8 cases of cystic renal cell carcinoma was watery density, 5 cases of cyst fluid density increased, uneven; 6 cases with different locations, varying degrees of plaque calcification; 10 cases of wall thickening or uneven thickness, 4 cases with uneven thickness of the capsule separation, 5 cases with different sizes of soft tissue nodules; enhanced scanning of 10 cases of cyst wall and soft tissue interspaced mild to moderate enhancement in 3 cases of solid components significantly enhanced. Conclusion CT has certain clinical value in the diagnosis and differential diagnosis of cystic renal cell carcinoma.
