Cystic neoplasms of the pancreas are rare pancreatic tumors; nowadays they are diagnosed more frequently due to the spread of accurate imaging techniques. The WHO classification distinguishes serous cystic neoplasms (SCNs), mucinous cystic neoplasms (MCNs), intraductal papillary mucinous neoplasms (IPMNs), and solid pseudopapillary neoplasms (SPNs). Those with a greater potential for malignant transformation are MCNs, IPMNs of the main pancreatic duct, and SPNs; surgical resection is indicated for these neoplasms. SCNs and branch-duct IPMNs have a very low malignant potential, so long-term radiological follow-up is indicated. Pancreatic neuroendocrine tumors (NETs) present as cystic lesions in approximately 5 % of cases, with radiological features similar to SCNs, MCNs, or SPNs. Magnetic resonance imaging (MRI), completed with MR cholangiopancreatography (MRCP) sequences and contrast administration, is the most important technique in the evaluation of cystic neoplasms of the pancreas.
