To evaluate the clinical features and CT findings of solid-pseudopapillary tumor (SPT) of the pancreas.

Nineteen cases of SPT proved pathologically were reviewed. The clinical data and MSCT findings were retrospectively evaluated including tumor size, location, and imaging features.

21.1% (4/19) of tumors showed fresh hemorrhage with slightly hyper-attenuation on pre-contrast CT. Calcification was noted in 26.3% (5/19) of tumors. Three types of SPT were classified according to the different ratio of cystic and solid components detected on CT images: tumor with predo-minant cystic component, tumor with predominant solid component and tumor with mixture of cystic and solid component. Tumor capsules were clearly depicted on CT image in tumor with predominant cystic component or tumor with mixture of cystic and solid component. Tumor capsule and solid component showed enhancement after contrast administration.

The clinical and CT findings of SPT of the pancreas are characteristic. CT can be helpful for the diagnosis of SPT.
