Common cystic pancreatic neoplasms: A comprehensive magnetic resonance imaging-based review of typical and atypical imaging features

Figure 16  Typical magnetic resonance imaging appearance of solid pseudopapillary neoplasm. A: Non-contrast computed tomography shows a heterogeneous lesion with small internal calcifications (arrow) of the pancreatic head; B: Axial single-shot T2-weighted image demonstrates a predominantly hyperintense mass with internal heterogeneity related to cystic and solid areas; C: Axial T1-weighted image shows intrinsic areas of high signal intensity consistent with hemorrhagic components; D and E: Axial post contrast-enhanced T1-weighted images in arterial and portal-venous phases, demonstrate progressive heterogeneous enhancement of the solid portions; F: Coronal post contrast-enhanced T1-weighted image confirms the encapsulated appearance and mixed solid-cystic architecture.
