摘　　要：目的:探讨胰腺浆液性囊腺瘤、黏液性囊腺瘤或囊腺癌具有鉴别诊断意义的CT征象。方法:回顾性分析经手术及病理证实的17例胰腺浆液性囊腺瘤、黏液性囊腺瘤或囊腺癌的CT表现,总结其特征性表现。结果:17例中浆液性囊腺瘤7例,黏液性囊腺瘤8例,黏液性囊腺癌2例。浆液性囊腺瘤呈分叶状轮廓者占85.7%(6/7),均为多囊状结构,其中最大囊直径小于2cm者占71.4%(5/7),出现病灶中心钙化者1例;黏液性囊腺瘤或囊腺癌位于胰体尾部者占90%(9/10),无分叶状轮廓,单囊者占80%(8/10),最大囊直径大于2cm者占90%(9/10)。囊内乳头状突起,囊壁厚薄不均,病灶内实性成分增多,多提示恶性。结论:胰腺浆液性囊腺瘤与黏液性囊腺瘤或囊腺癌的CT表现明显不同,多可做出诊断与鉴别诊断,但对于不典型表现的诊断存在困难。Objective：To evaluate the CT features of serous cystadenomas,mucinous cystadenomas or cystadenocarcinomas of the pancreas for differential diagnosis.Methods：CT appearances of 17 cases with serous cystadenomas and muci-nous cystadenomas or cystadenocarcinomas of the pancreas confirmed by surgery and pathology were retrospectively analyzed.Results：This study included 7 cases of serous cystadenomas,8 cases of mucinous cystadenomas and 2 cases of cystadenocarcinoma.85.7% （6/7） of serous cystadenoma of the pancreas presented as a lobulate and multicystic lesion,71.4% （5/7） of the lesions contained cyst with a diameter less than 2cm.Central calcification was observed in one case.90% （9/10） of the mucinous cystadenoma/cystadenocarcinoma were located in the body and tail of the pancreas.80%（8/10） of the lesions appeared as a single cyst with a smooth margin.90% （9/10） of the lesions contained the largest cyst with a diameter over 2cm.Uneven thickness of cystic wall,papillary excrescence and much solid substance in the lesion indicated malignancy.Conclusion：CT characteristics of serous cystadenomas and mucinous neoplasms or cystadenocarcinomas of the pancreas are quite different,which is helpful for diagnosis and diferential diagnosis.However,atypical CT appearances may compromise its diagnostic accuracy.
