Abstract    Cystic pancreatic neoplasms are often an incidental finding, the frequency of which is increasing. The understanding of such lesions has increased in recent years, but the numerous types of lesions involved can hinder differential diagnosis. They mainly include serous cystic neoplasms (SCN), mucinous cystic neoplasms (MCN), intraductal papillary mucinous neoplasms(IPMN), and solid pseudopapillary neoplasms (SPN). Several of cystic pancreatic neoplasms can undergo malignant transformation and, therefore, require differentiated radiological and surgical managements. Because of minimally invasive approach, limited surgical procedures like enucleation, pancreatic middle segment resection or duodenum-preserving total or subtotal pancreatic head resection are recommended. The indication for follow-up or surgical intervention for patients with pancreatic cystic neoplasms should be controlled reasonably.
