Solid pseudopapillary neoplasm (SPN) in a 17-year-old female with liver metastases (Fig. 4B–D: Courtesy of the Department of Diagnostic and Interventional Radiology and Pediatric Radiology, Klinikum Schwabing, Munich, Germany). (A) Photograph shows macroscopic appearance of SPN of the pancreatic head. The 7 cm × 6 cm × 6 cm measuring tumor with a thin capsule shows an infiltration of the duodenal wall. The tumor itself is mainly solid with hemorrhages and few necrotic areas. (B) T2-W HASTE sequence shows a large, mostly homogeneous, well-defined rounded pancreatic mass with low signal intensity. (C) On fat-suppressed T2-WI in the axial plane the lesion appears more heterogeneous, mostly hyperintense. (D) Axial fat-suppressed T2-WI shows hyperintense liver metastasis (arrow).
