7例乳头状肾癌的动态增强CT表现并文献复习
Progress in Modern Biomedicine(2013)
Abstract
目的:总结乳头状肾细胞癌(papillary renal cell carcinoma,PRCC)的动态增强CT表现,并对乳头状肾细胞癌的临床特点和鉴别诊断进行文献复习。方法:回顾性分析7例经病理证实的乳头状肾细胞癌的临床、手术及CT资料。结果:7例均为单发肿块,位于右肾5例,位于左肾2例,CT平扫表现为境界清楚或欠清楚的圆形或椭圆形结节或肿块,病变直径0.8 cm~3.5 cm,平均1.8cm,瘤体小时(≤3 cm)密度较均匀,无囊变和坏死;瘤体较大时(≥3 cm)常出现坏死、囊变。肿瘤强化程度较低,皮髓质期至实质期渐进性轻度增强,排泄期密度略降低。结论:乳头状肾细胞癌的CT表现有一定特征,多呈渐进性轻度强化,与其它类型肾癌不同,可为临床决定手术方式提供依据。
