摘要
目的:探讨乳头型壶腹癌的MRI和磁共振胰胆管成像(MRCP)表现及诊断价值。材料与方法:回顾性分析经病理组织学检查证实的17例乳头型壶腹癌的MRI及MRCP表现,分析胆总管壶腹部病灶、胆管扩张形态、梗阻端形态以及胆管、胰管与十二脂肠之间的关系。结果:17例均清晰显示十二脂肠乳头、壶腹部局限性强化的充盈缺损团块影,肿瘤直径为1～4.2cm,平均2.1cm。所有病例均可见肝内胆管扩张、胆囊增大、胆总管扩张和12例胰管的扩张,1例伴胰体尾部的明显萎缩。结论:MRI结合MRCP不仅能准确确定梗阻平面,还能显示十二脂肠乳头部壶腹癌强化的肿块影,可作为乳头型壶腹癌的首选检查方法。
Purpose： To investigate the manifestations and the value of MRI in combination with MR cholangio-pancreatography in the diagnosis of polypoid ampullaly carcinoma. Materials and Methods： The MRI and MRCP findings of polypoid ampullary carcinoma in 17cases proved by pathology were retrospectively analyzed. The changes of duodenal papilla region, the dilation pattern of pancraetiocbiliary duct as well as the obstruction ending of bile duct, the relationgship between pancreaticobillary duct and duodenum were investigated. Results： All cases could display an enhanced mass as local filling defect at site of the duodenal Vater＇s ampulla, the tumors ranged in size from lcm to 4. 2 cm with mean of 2. 1cm, all were accompanied with dilated intrahepatic and common bile duct, enlarged gallbladder , 12 cases with dilated pancreatic duct, and I eases which had marked atrophy of the pancreatic body and tail. Conclusion： The MRI and MRCP could not only accurately define the level of obstruction, but also demonstrate an enhanced mass, is the modality of choice in the diagnosis of polypoid ampullary carcinoma.
