26-year-old woman with recurrent acute pancreatitis.

A, Non–secretin-enhanced MRCP is nondiagnostic for divisum because duct in pancreas head is not clearly visualized.

B, Secretin-enhanced MRCP clearly shows continuation of main duct by dorsal duct (arrow), in keeping with divisum. Dilated end of dorsal duct (Santorinicele, black arrowhead) may suggest increased pancreatic ductal pressure. Note that exocrine output predominantly fills duodenal bulb (white arrowhead) and some of descending duodenum, but not entire duodenum, indicating suboptimal exocrine response to secretin.
