Abstract

Objective To study the MSCT findings of solid pseudopapillary tumors of the pancreas(SPTP), in order to improve the diagnostic level. Methods The findings of MSCT imaging in 9 cases with pathologically proved SPTP were analyzed retrospectively. One patient was male, 8 patients were female, age from 10 to 52 years old, with average of 32 years old. All patients were underwent CT plain scans and multiple phase enhanced scans. Results 6 tumors were located in tail of pancreas,2 in head and 1 in body. 8 lesions were oval and 1 lesion was lobular, with the diameter ranging from 4.7 to 12.0 cm (mean 6.8cm). 6 cases were solid-cystic tumors, 2 cases were cystic tumors and 1 was pure solid tumor. Hemorrhages were seen in 4 cases on CT images. Calcification were seen in 6 cases, with patchy calcification around in 5 cases, and eggshell calcification in l case. The solid part of the tumors were enhanced slightly in the arterial phase and markedly in the portal venous phase, presenting gradual and central enhancement. Conclusion There are some characteristics on MSCT findings of SPTP. The correct imaging diagnosis is possible based on clinical characteristic and CT findings.
