摘要
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。
Objective： To summerize the dynamic contrast-enhanced CT image of papillary renal cell carcinoma（PRCC） and review the lieratures about the clnical charateristics and differential diagnosis of PRCC. Methods： The clinical, surgical and CT information of 7 cases of papillary renal cell carcinoma confirmed by pathology were retrospectively analyzed. Results： 7 cases of solitary masses, located in the fight kidney of 5 cases, in the upper-left 2 cases of kidney, plain CT scan as clear or not clear, round or oval-shaped nodules or masses, lesions diameter 0.8 cm-3.5 cm, an average of 1.8cm, tumor hours （~ 3cm） density is uniform, not cystic and necrosis. The tumor is large （~ 3 era） frequent necrosis and cystic. Tumor strengthening low level between Medullary progressive mild increase in real terms, slightly lower drainage density. Conclusion： CT manifestations of papillary renal cell carcinoma has a certain feature, progressive mild enhancement, and other different types of renal carcinoma, surgery provides the basis for clinical decisions.
