From: MR features of primary and secondary malignant lymphoma of the pancreas: a pictorial review
A 57-year-old man with secondary pancreatic lymphoma. a Axial T2-weighted image shows diffuse pancreatic swelling with pancreas parenchyma homogeneously hypointense relative to spleen. b Axial T1-weighted image shows that the majority of the pancreas is heterogeneously hypointense with a hyperintense area (white arrow), representing residual normal pancreatic parenchyma, in the centre of the lesion. c Portal phase of dynamic contrast-enhanced MR image shows poorly enhanced peripheral area mimicking capsule-like rim (white arrowheads). The rim however does not have the characteristic appearance of the typical hypointense, uniform thickness rim in autoimmune pancreatitis
