胰腺导管内乳头状黏液瘤(Intraductal papillary mucinous neoplasm,IPMN)是由胰腺导管内产生粘液的上皮细胞呈乳头状增殖形成的低度恶性肿瘤。其生长缓慢、临床表现多样、命名及分型标准复杂混乱、影像学具有一定的特征且检查手段众多、治疗需采用不同方案。因此,本文从临床特征、病理分型及生物学行为、影像特征及影像诊断方法、治疗及预后等方面就其相关进展进行综述。 Intraductal papillary mucinous neoplasm (IPMN) is a low-grade malignant tumor formed by papillary hyperplasia of mucus-producing epithelial cells in the pancreatic duct. Its slow growth, diverse clinical manifestations, naming and classification of the standard complex chaos, imaging has some characteristics and means of examination many, the treatment need to use different programs. Therefore, this review summarizes the progress of clinical features, pathological classification and biological behavior, imaging features and diagnostic methods, treatment and prognosis.
