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

Figure 14  Small mucinous cystic neoplasm. A and B: Axial and coronal T2-weighted images show a small (< 3 cm), well-circumscribed cystic lesion in the pancreatic body–tail region, with homogeneous high T2 signal intensity and subtle internal septations; C: Thick-slab magnetic resonance cholangiopancreatography demonstrates a unilocular cystic morphology without communication with the main pancreatic duct; D: Diffusion weighted imaging (b = 1000 second/mm²) shows no evidence of diffusion restriction, with mild hyperintensity of the cyst wall; E: Axial T1-weighted image shows low signal intensity, without intrinsic T1 hyperintensity; F and G: Post-contrast T1-weighted images depict minimal enhancement of thin internal septa, without enhancing mural nodules.
