A 69-year-old man suffering from recurring epigastralgia for over 30 years presented to our department with epigastric pain. Contrast-enhanced computed tomography revealed acute pancreatitis, dorsal pancreatic duct dilation, aplasia of the pancreatic uncinate process, and intestinal malrotation. Magnetic resonance cholangiopancreatography revealed the pancreas divisum and showed the ventral pancreatic duct was located more cranial than the dorsal pancreatic duct, which we diagnosed as ventral pancreas malrotation. It is believed that this occurred during the development of the pancreas, when rotation of the ventral pancreas was hindered by intestinal malrotation and the ventral pancreas fused with the dorsal pancreas at the upper pancreatic head. Pancreatitis resolved without drainage of the dorsal pancreatic duct via the accessory papilla. The coexistence of ventral pancreas malrotation and pancreas divisum has not been previously reported, and findings were indicated by detailed image evaluations.
