Abstract: The particularity of pancreatic anatomical location, the complexity of secretory function, and the diversity of pathology lead to complex imaging findings of pancreatic tumors. The common pancreatic tumors include pancreatic ductal adenocarcinoma, solid pseudopaillary neo-plasm, neuroendocrine neoplasm, intraductal papillary mucinous neoplasm, serous cystadenoma and mucinous cystic neoplasm. Atypical imaging findings are important reasons for misdiagnosis. Based on relevant clinical experiences, the authors analyze and summarize the atypical imaging findings of six kinds of common pancreatic tumors, aiming to improve radiologists and clinicians comprehensive understanding of pancreatic tumors.
