Summary
Imaging features of solid-pseudopapillary neoplasm of the pancreas (SPNP) in children can aid diagnosis. Accurate preoperative diagnosis of SPNP is possible without biopsy, which is crucial for chemoresistant pediatric tumors.
Area of Science:
- Pediatric Radiology
- Oncology
Background:
- Solid-pseudopapillary neoplasm of the pancreas (SPNP) is a rare pancreatic tumor predominantly affecting young women.
- Accurate preoperative diagnosis is essential for appropriate management and to avoid unnecessary procedures.
Observation:
- Two pediatric cases of SPNP were analyzed for characteristic imaging findings.
- Observed features included tumor heterogeneity, a pseudocapsule, and internal hemorrhage.
Findings:
- The imaging features observed in these cases are consistent with the known pathology of SPNP.
- These findings suggest that SPNP can be accurately diagnosed preoperatively using imaging modalities.
Implications:
- Preoperative diagnosis of SPNP in children can be achieved through imaging, potentially obviating the need for biopsy.
- Avoiding biopsy is critical in chemoresistant tumors like SPNP to minimize risks of tumor seeding.
