磁共振成像评估胰腺导管内乳头状黏液瘤良恶性诊断价值

Research on the value of diagnosis of malignant and benign by using MRI to assess intraductal papillary mucinous tumor(IPMN)

目的:探讨磁共振成像(MRI)评估胰腺导管内乳头状黏液瘤(IPMN)良性及恶性的诊断价值。方法:回顾性分析经手术病理证实的10例胰腺导管内乳头状黏液瘤的MRI表现,以评估其良恶性的价值。结果:入组的胰腺导管内乳头状黏液瘤病例,3例轻度不典型增生(良性)中1例位于胰头部;2例位于胰体部,表现为主胰管局部轻度扩张>5 mm<10 mm;4例中度不典型增生(交界性)中2例位于胰头,2例位于胰尾部,主胰管均扩张>10 mm<15 mm,为分叶状囊性肿块,内部有或无分隔和乳头状突起;3例重度不典型增生伴局部浸润癌(恶性),均位于胰头部,胰管明显扩张>15 mm,为不规则囊实性肿块,其中1例发生肝脏多发转移。结论:MRI评估胰腺导管内乳头状黏液瘤良性及恶性有独特优势。

Objective： To investigate the MRI assessment of intraductal papillary mucinous tumors （IPMN） in the diagnosis of benign and malignant. Methods：Retrospectively to evaluate the value of benign and malignant MRI performance analysis confirmed that from 2011 to 2014 pathology in 10 cases of intraductal papillary mucinous tumors. Results：Three cases of mild atypical hyperplasia（benign）, 1 cases were located in the head of pancreas, 2 cases in the pancreatic body, the performance of the main pancreatic duct dilatation of local mild greater than 5 mm and less than 10mm;4 cases of moderate dysplasia（borderline）, 2 cases were located in the pancreatic head, 2 cases in the tail of the pancreas were greater than 10mm and less than 15 mm, the expansion of the main pancreatic duct, lobulated cystic mass, internal with or without separation and papillae; 3 cases of severe atypical hyperplasia with local infiltration cancer（malignant）, are located in the head of pancreas, pancreatic duct dilated obviously greater than 15mm, the irregular cystic mass, of which 1 case had liver metastasis. Conclusion： MRI assessment of intraductal papillary mucinous tumor has unique advantages and important role of.
