Santorinicele without Pancreas Divisum: Diagnosis with Multi-Detector Row CT and MR Cholangiopancreatography

A santorinicele is a cystic dilatation of the dorsal pancreatic duct at the minor papilla, and has been reported in patients with pancreas divisum and pancreatitis. Santorinicele without pancreas divisum is extremely rare, with only one case being previously reported. We present here a case of santorinicele that was observed as a cystic dilatation of the distal dorsal pancreatic duct at MCDT, and had communication between the ventral and dorsal pancreatic ducts. Additionally, MRCP and ERCP firmly confirmed the presence of a santorinicele.
