A 48-year-old man presents with severe epigastric pain, nausea, vomiting, and diarrhea.

Fig. 39.1 (A–F) Axial and coronal contrast-enhanced CT images show pancreatic calcification along with dilatation of the pancreatic duct. There is a multiloculated lesion seen in the anatomical plane between the pancreatic head and duodenum (pancreaticoduodenal groove). Postcholecystectomy clips are noted.
