Mucinous Non-neoplastic Cyst of the Pancreas.

Cystic neoplasms of the pancreas consist of a wide range of pathological entities and are being detected more frequently due to advances in cross-sectional imaging modalities and increasing numbers of periodic health checkups. The majority of pancreatic cystic neoplasms are intraductal papillary mucinous neoplasms, serous neoplasms, and mucinous cystic neoplasms, but recently, rare cases of mucinous non-neoplastic cyst of the pancreas (MNCP) have been reported, and despite the availabilities of modern imaging systems, such as MRI and CT, the differentiation of non-neoplastic and neoplastic cysts remains challenging. Herein, we report our experience of a 65-year-old male case with an MNCP.
