Type 1 autoimmune pancreatitis with concurrent pancreatic ductal adenocarcinoma. Axial pre-enhanced (a), arterial (b), venous (c) phase on CT and axial T2WI (d), T1WI (e), pancreatic (f), portal venous (g) and delayed venous (h) phase on MR imaging showed a focal lesion in the pancreatic head (straight black arrows). It appeared as low-density on enhanced CT images (b and c). The imaging characteristic of rim enhancement was noted on enhanced MR images (f, g and h), which was not obvious on CT. Distal pancreatic parenchymal atrophy was observed (straight white arrows on a-h). Kidney involvement was also seen (curved white arrows on b and c)
