Abstract
A 61-year-old woman visited to the hospital because of back pain. Abdominal US showed a cystic mass about 45mm in diameter of the pancreas head which was not indicated the previous yearʼs medical examination. Abdominal enhanced CT showed a multilocular cystic lesion 43mm in diameter of the pancreas head with central calcifications and peripheral large and small cysts. MRCP showed a high intensity multilocular cystic lesion 43mm in diameter of the pancreas head on T2 intensity. ERCP showed a slight exclusion by the cyst. Though, the cystic lesion had no communication with the main pancreatic duct. Pylorus-preserving pancreaticoduodenectomy was performed with the diagnosis of serous cystic neoplasm of the pancreas head. Histopathological studies revealed serous cystadenoma of the pancreas with single cuboidal epithelium. Epithelium consisting the cyst showed no atypical cells or abnormal mitosis. However, one part of the epithelium showed back to back–like structures, which suggests malignancy. We report a case of a serous cystadenoma of the pancreas.
