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

Figure 17  Atypical small solid variant of solid pseudopapillary neoplasm. A: Axial T2-weighted image shows a small, well-defined solid lesion with mildly hyperintense signal in the pancreatic body; B: Axial T1-weighted image demonstrates low signal intensity; C: Thin-slab magnetic resonance cholangiopancreatography shows only poor hyperintensity (arrow), reflecting the predominantly solid nature of the lesion; D: Diffusion weighted imaging (b = 1000 second/mm²) demonstrates high hyperintensity on high b values (arrow). In a 34-year-old woman, this homogeneous solid appearance represents an atypical presentation of solid pseudopapillary neoplasm and may mimic a pancreatic neuroendocrine tumor.
