Pancreatic tumors are rare in children and adolescents.

Recently, a study published in the journal European Radiology used computed tomography and magnetic resonance imaging features to differentially diagnose pancreatic blastoma (PB) and solid pseudopapillary tumors (SPNs) of the pancreas in children, which is an accurate preoperative diagnosis.

The clinical and imaging data of 20 cases of SPN and 14 cases of PB confirmed by surgery or biopsy were retrospectively analyzed.

Age ≤5 years, elevated serum alpha-fetoprotein (AFP), large volume, unclear borders, calcification, no bleeding, intratumoral vascular, peripancreatic vascular infiltration, and distant metastasis can distinguish PB from SPN (P <0.

Picture an eight-year-old girl with abdominal pain, pathologically confirmed as SPN.

The table shows the sensitivity and specificity of each significant index in distinguishing PB and SPN.

This study shows that age ≤5 years, elevated serum alpha-fetoprotein (AFP), increased volume, unclear borders, calcification, no bleeding, intratumoral blood vessels, peripancreatic vascular invasion, distant metastasis, and decreased ADC value are helpful To distinguish between PB and SPN, provide more clinical and imaging support for the accurate identification of the two diseases by preoperative imaging examination.
