胰腺转移性肾透明细胞癌的CT表现

CT manifestations in metastatic renal clear cell carcinoma of the pancreas

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.
