The patient was a 66-year-old woman with the chief complaint of numbness of her both hands without any digestive symptoms. Abdominal ultrasonography and CT showed a tumor picture, ERP did an exclusive picture of the pancreatic duct, and a slightly hypervascular pattern by angiography. The patient was diagnosed as having a cystadenocarcinoma of the pancreatic body and operation was carried out. The tumor disclosed 4×4.5 cm in size, clearly demarcated picture, cleavage surface with many microcysts containing serosity like substance.
