CT scan confirmed the presence of the pancreatic mass (Figures 1(a) and 1(b)).
NMR evaluation of pancreatic lesion. (a) Diffusion weighted imaging (DWI) axial sequence shows a hyperintense pancreatic body mass with restricted apparent diffusion coefficient (ADC) value, confirmed in ADC map; (b) single shot axial T2-weighted fat sat image shows pancreatic body mass isointense to liver parenchyma; (c) single shot coronal T2-weighted image shows dilated extrahepatic biliary duct; (d) as shown in (b), with the indication of diameter of the lesion (4 centimeters); (e) 3D maximum intensity projection (MIP) coronal image showing dilated intra- and extrahepatic biliary ducts without evidences of middle segment of Wirsung duct; (f) T2-weighted radial big slab image of the same condition presented in (e).

Figure 2, this lesion was highly suspicious to be of inflammatory origin. Furthermore, the salivary gland swelling and the diffuse adenopathy of the patient were suggestive of an immunological disorder, with focal pancreatic involvement.
