Capsulated NEN. MRI study: the pancreatic head lesion is slightly hypointense on T1-weighted fat-saturated axial images (a) and presents diffusion restriction (b) on DWI (b = 800). In the late hepatospecific phase (c) with contrast medium (Gd-BOPTA), the common bile duct (C) is clearly visible and not dilated, since it is displaced but not compressed by the pancreatic head mass
