From: MR features of primary and secondary malignant lymphoma of the pancreas: a pictorial review
A 56-year-old man with secondary pancreatic lymphoma, biopsy-proven follicular lymphoma. a Axial fat-suppressed T2-weighted image shows invasively spreading hyperintense retropancreatic mass (white arrowheads) and heterogeneously hyperintense pancreas (white arrow). b Axial fat-suppressed T1-weighted image shows hypointense retropancreatic mass (white arrowheads) pushes pancreatic parenchyma anteriorly. Involved pancreatic parenchyma is seen as a heterogeneously hypointense area (white arrow). c Haematoxylin-eosin-stained histologic section (original magnification, ×200) shows the tumour with atypical large lymphoid cells aggregated focally (white small arrows). The tumour cells are stained positive for CD10 antigen and bcl2 gene by immunohistochemical analysis (not shown)
