Further contrast MRI scan of the abdomen (Fig. 1) revealed sharp margins of the heterogeneously enhancing mass of the pancreatic head and uncinate process abutting the second portion of the duodenum.
T2-weighted axial MRI demonstrates a well-defined mass (arrow) with high T2 signal components that has borders approximating the second portion of the duodenum and the uncinate process.
