乳头状肾细胞癌的CT表现与手术病理对照

目的：分析乳头状肾细胞癌的cT影像，探讨其相对特异的CT表现。方法：回顾性分析10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：全部病例均为单发肿块，位于右。肾7例，位于左肾3例，CT平扫肿瘤呈圆形或椭圆形，边缘清楚或欠清楚。病变长径1．0～4．5cm，平均2．5cm。瘤体小时（冬3cm）密度较均匀，无囊变和坏死：瘤体较大时（≥3cm）常出现坏死、囊变。肿瘤强化程度较低，三期呈渐进性轻度增强，特别是排泄期密度略降低。结论：与其他亚型。肾癌相比，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，其确诊可为手术方式的选择提供依据。

Comparative Study of CT Findings and Operation Pathology of Papillary Renal Cell Carcinoma

Objective： CT image analysis of papillary renal cell carcinoma, and explore the specific CT findings. Methods： Retrospective analysis of 10 cases, papillary renal cell carcinoma confirmed by operation and CT data. Results： All the cases were solitary mass, located in right kidney in 7 cases, in the left kidney in 3 cases, CT scan, tumors were round or oval, clear edge or less clear. Lesion diameter was 1.0-4.5 cm, average 2.5 cm. The tumor hours （〈 3 cm） density is uniform, no cystic degeneration and necrosis; tumor is large （_〉 3 cm） often appear necrosis, cystic change. Tumor enhancement degree is low, the three stage is progressive mild enhancement, especially the excretory phase density is slightly reduced. Conclusion： Compared with other subtypes of renal cell carcinoma, CT manifestations of papillary renal cell carcinoma has certain features, mostly progressive enhancement, the diagnosis can provide the basis for the selection of operation.
