Incidence
- The reported prevalence of PCNs in computed tomography (CT) is 2.1–2.6% and for magnetic resonance imaging (MRI) this is 13.5–45%
Types
- Mucinous cysts - precursors for HGD/IC and thus require resection or surveillance)
- IPMN- Intraductal papillary mucinous neoplasm
- IOPN - Intraductal oncocytic papillary neoplasm
- ITPN- Intraductal tubulopapillary neoplasm
- MCN - Mucinous cystic neoplasms
- Serous cyst neoplasms
- Serous cystadenoma
- Pseudocysts
- Solid pseudopapillary neoplasms - can have cystic component due to degeneration
