Figure 2 Image findings from 55-year-old man with AIP who had high serum IgG4 concentrations. A pancreatic stone appeared after several recurrences during 10-year follow-up. (A) ERP at onset showed irregular narrowing of the head region of the pancreas; (B) 10 years after onset, ERP image of MPD showed narrowing in the body and dilatation in tail region. (C) Pancreatic stone appeared in the body and tail regions of MPD after reduction in prednisolone dose. For comparison, lower panels show image findings for 65-year-old woman with AIP who had normal serum IgG4 concentrations during 10 years of follow-up. (D) ERP performed at onset shows diffuse irregular narrowing of MPD; (E) MRI and (F) MRI of pancreas showed no progression or duct changes in 10 years of follow-up.
