Magnetic resonance cholangiopancreatography (MRCP) of the abdomen showing pancreas divisum: (A) Indicates the dorsal pancreatic duct (which is the most prominent duct in pancreatic divisum) as it crosses over the common bile duct. There are obvious dilatations of this dorsal pancreatic duct as shown in this MRCP, the largest being 6.1 mm, consistent with chronic pancreatitis. (B) Indicates part of the dorsal duct, where it drains directly into the duodenum through minor papilla. The inherently small diameter of the minor papilla causes increased pressure in the dorsal pancreatic duct, as shown in this MRCP. (C) Indicates the common bile duct, which is joined by ventral pancreatic duct before draining into duodenum through the major papilla. (D) Indicates the short remnant or filamentous communication between the ventral and the dorsal duct that define this as a type III pancreatic divisum. | Kuzel, A. R., Lodhi, M. U., & Rahim, M.
