description: "A congenital anomaly of the pancreas that results from failed fusion of the dorsal and ventral ducts during embyological development. Three variants have been described: type 1 or classical divisum in which there is total failure of fusion; type 2 in which dorsal drainage is dominant in the absence of the duct of Wirsung; and type 3 or incomplete divisum where a small communicating branch is present."
