摘要
目的:探讨胰腺转移性肾透明细胞癌的螺旋CT平扫和动态增强的表现及其特征。方法:对经术后病理证实的5例胰腺转移性肾透明细胞癌的CT表现进行回顾性分析并文献复习。结果:5例均为多发病灶,共14个病灶,CT影像显示平扫呈等或低密度,动脉期呈明显强化,门脉期及延迟期强化幅度下降明显,呈速升速降特征。结论:胰腺转移性肾透明细胞癌的CT多表现为多发病灶,动脉期明显强化,具有一定的特征性,结合病史及临床资料可以提高诊断的准确率。
Objective: To discuss the CT characteristics of pancreatic metastatic renal clear cell carcinoma by conventional spiral CT and dynamic enhanced CT examinations. Methods: CT manifestations in 5 cases of pancreatic metastatic clear cell renal cell carcinoma confirmed by postoperative pathology were analyzed retrospectively and literature review. Results: There were multiple lesions, a total of 14 lesions in the pancreas. CT image displayed the lesions to be iso-or hypo-density, which enhanced obviously in arterial phase, while the enhanced amplitude decreased significantly in portal venous and delayed phases, with a quick lift quick down characteristics. Conclusion: In pancreatic metastatic clear cell renal cell carcinoma, CT showed multiple lesions, obvious enhancement in arterial phase, and had certain characteristics, when combined with the histo-ry and clinical data, it can improve the diagnostic accuracy rate.
