OBJECTIVE. The purpose of this article is to describe the sonographic, CT, and MRI features of primary malignant pancreatic tumors of childhood. CONCLUSION. Most children with a pancreatic tumor present with a solid pseudopapillary tumor that is usually well marginated and has solid and cystic areas surrounded by a fibrous capsule. Pancreatoblastoma is more aggressive than solid pseudopapillary tumor. The imaging features are those of a large heterogeneous tumor.
