Overview
Solid and pseudopapillary epithelial neoplasm (SPEN) accounts for approximately 1% of pancreatic neoplasms. The high incidence in young women (mean, 24 years old) is especially noteworthy (Daughter tumor). Distinctive clinical features include eosinophilia and polyarthralgia. It is a low-grade malignancy. Resection is usually curative.
The imaging findings are,
- Can be solid, but they often present as thick-walled cysts on CT and sonography.
- Attenuation is high when hemorrhage occurs.
- CT will show peripheral or central stippled calcification in some lesions.
- Tumor vascularity is moderate
