Pancreas divisum
Pancreas divisum The pancreas in itīs early embryonic development consists of a dorsal and a ventral part. In case of incomplete fusion of both parts during the later phases of embryonic development, a pancreas divisum results. A pancreas divisum consists of a cranial minor duct (Duct of santorini) draining most of the organ through the minor papilla and a lower very short major duct (Duct of wirsung) draining only a small portion of the pancreatic head (fig) through the major papilla. The cloudy contrast enhancement corresponds to the opacified parenchyma of the pancreatic head.
Move the mouseīs arrow onto the picture to colour the pancreatic duct.
Pancreas divisum - partial
Panceas divisum - partial In this case both the Duct of wirsung (2) and the duct of santorini (1) can be filled by canulation of the major or the minor papilla. Thus the fusion of the dorsal and ventral pancreatic root has been incomplete.
