Figure 35. Intraductal papillary mucinous tumor in patient presenting with recurrent pancreatitis. (A, B) Contrast-enhanced CT scan (A) and corresponding axial HASTE T2-weighted iamge (B) clearly demonstrate a ventral pancreatic duct enlargement (arrows) and no tumor. (C, D) MRCP (C) and corresponding ERCP (D) better demonstrate the extent of the intraductal lesion, its irregular margins, and filling defects (arrows), corresponding to mucus production and papillary hyperplasia.
