Chapter 9 - Pancreatic cystic lesions

Abstract

Pancreatic cystic lesions are rare, comprising 1%–2% of pancreatic neoplasms and 50% of pancreatic cystic lesions. The main types of pancreatic cystic lesions are serous cystic neoplasms, mucinous cystic lesions, solid pseudopapillary neoplasms, and intraductal papillary mucinous neoplasms (IPMNs). IPMNs are increasingly diagnosed. Diagnostic modalities include cross-sectional imaging, ERCP and EUS with biopsy, cytology, and molecular marker analysis. The Sendai criteria are instrumental in risk stratification of these lesions. The mainstay of treatment is surgical resection.
