Computed tomography imaging features of small (≤ 3 cm) solid pseudopapillary tumors of the pancreas

Solid pseudopapillary tumors (SPTs) of the pancreas is a low-grade malignant tumor, accounting for only 1–2.5% of all pancreatic tumors. In particular, small (≤ 3 cm) SPTs do not often have typical computed tomography (CT) features, making them easily misdiagnosed with other solid tumors and eventually affecting the choice of treatment method.
