Abstract:
Objective To study MRI features of solid-pseudopapillary tumors of pancreas(SPTP).Methods MR findings of 3 patients with histopathologically proven SPTP were retrospectively analyzed.Results The mean diameter of these tumors was 4.5cm(3.5～8cm).One tumor was predominantly composed of cystic portions,2 tumors were composed of predominantly solid and some cystic portions.Fibrous septa was seen in cystic area in 1 case.One cystic tumor showed low signal intensities on T1WI and high singal intensities T2WI.The solid portions of mass showed moderate hypointensity on T1WI,and moderate hyperintensity on T2WI,and heterogeneous obvious enhancement on T1WI MRI in 2 cases.Conclusion There are some characteristics in MRI manifestation of SPTP.The disease might be correctly diagnosed combined with the clinical feature,and should be differentiated from nonfunctioning islet cell tumor,mucinous cystadenoma or cystcarcinoma of the pancreas,etc.
