目的探讨胰腺先于发现原发肿瘤的单发性转移瘤与胰腺癌在鉴别诊断中的价值。资料与方法回顾分析均经病理证实后的先于发现原发肿瘤的单发性转移瘤35例与均经病理证实后的胰腺癌66例,二者所有病例均行CT平扫和增强扫描,所有病例图像资料汇集PACS工作站进行盲法分析。结果胰腺先于发现原发肿瘤的单发性转移瘤与胰腺癌在病变的形态、边缘、分布、胰胆管扩张、周围血管侵犯密度与强化及胰实质萎缩方面有一定的差异。结论 CT对先于发现原发肿瘤的单发性转移瘤与胰腺癌的鉴别诊断很有帮助。
Objective To investigate the value of pancreatic adenocarcinoma in the differential diagnosis between solitary metastasis of primary tumor and pancreatic cancer. Materials and Methods Retrospective analysis were pathologically confirmed after the primary tumor was found in 35 cases of solitary metastasis and pathologically confirmed pancreatic cancer in 66 cases, both cases of CT scan and enhanced scanning, All cases image data collection PACS workstation for blind analysis. Results The pancreatic adenocarcinoma had a certain difference from that of primary pancreatic adenocarcinoma in the form of primary pancreatic adenocarcinoma, morphology, margins, distribution, pancreaticobiliary dilatation, density and enhancement of peripheral vascular invasion and pancreatic parenchyma. Conclusion CT is helpful in the differential diagnosis of solitary metastasis and pancreatic cancer prior to the discovery of the primary tumor.
