摘　　要：目的探讨胰腺神经内分泌癌的影像学表现。方法回顾性分析2007年6月至2011年12月期间四川大学华西医院经手术及病理学检查确诊为胰腺神经内分泌癌的7例患者的影像学资料。观察肿瘤的边界、密度及强化特征。结果 7例中肿瘤位于胰头部2例、体部2例、尾部2例及体尾部1例。7例肿瘤形状均不规则,其中5例边界不清。推注对比剂后5例肿瘤表现为低密度强化,2例为等密度强化。2例肿瘤见远端主胰管扩张。未见远处转移或淋巴结侵犯。结论胰腺神经内分泌癌的影像学表现具有一定特点,其和胰腺癌鉴别诊断较难。Objective To evaluate the imaging features of pancreatic neuroendocrine carcinoma（PNEC）.Methods The imaging data of 7 patients with PNECs proved by surgery and pathology in West China Hospital of Sichuan University from Jul.2007 to Dec.2012 were retrospectively analyzed.The boundary,density,and strengthening features of tumor were observed.Results Seven tumors were found in all patients with 2 in pancreatic head,body,and tail,respectively.There was 1 tumor in pancreatic body and tail too.Five tumors were with unclear boundary.Five tumors had hypodense enhancement and 2 had isodense enhancement.Two cases had distal pancreatic duct dilation.None of them had liver metastases or lymph node involvement.Conclusion PNEC has certain characteristics on imaging.It is difficult to distinguish diagnosis from pancreatic cancer.
