Objective To investigate the CT and MR imaging manifestation of rare pancreatic tumors in order to deepen the understanding of their imaging characteristics and improve the diagnostic accuracy. Methods Clinical and image date of 34 cases with rare pancreatic tumors proved by surgery and histopathologically were analyzed retrospectively. Including neuroendocrine tumors of the pancreas (NETP,n=13), solid-pseudopapillary tumors of pancreas (SPTP,n=10), intraductal papillary mucinous neoplasms (IPMN,n=2), serous cystadenoma (SCA,n=7), and mucinous cystadenoma (MCA,n=2). Examined by CT in 19 cases, by MRI in 11 cases, examined by CT and MRI at the same time in 4 cases. The characterized imaging features of each kind of tumors were analyzed emphatically. Results Of the 13 cases of NETP, solid lesions in 6 cases, predominantly soild in 4 cases, predominantly cystic in 3 cases. Homogenous enhancement in 6 cases, heterogeneous enhancement in 7cases, the soild constituent of all cases were showed moderate to marked enhancement. Of the 10 cases of SPTP, predominantly soild in 2 cases, soild and cystic in 5 cases, predominantly cystic in 3 cases. The solid part of 10 cases presented as gradually enhancement, 2 cases appeared hemorrhage, 1 case appeared stippled calcification. Of the 2 cases of IPMN, both of them were combined type, showed multilocular cystic tumors due to the dilated of the pancreatic duct. Of the 7 cases of SCA, microcystic partten in 3 cases and single cyst partten in 4 cases, showed unilocular or multilocular cystic with clear boundary. The 2 cases of MCA, showed unilocular cystic with clear boundary. Conclusion Different histological types of pancreatic rare tumor appeared different kinds of imaging characteristic, we may improve the diagnostic accuracy by analyzing their features.
