Abstract

Characteristic imaging findings, diagnostic pitfalls, and differential diagnoses of cystic lesions of the

pancreas were described. It is important not to mischaracterize branch duct intraductal papillary

mucinous neoplasm (IPMN) as serous cystic neoplasm (SCN). In addition, care should be taken for the

development of pancreatic ductal adenocarcinoma concomitant with IPMN, especially for follow-up

cases. Furthermore, the radiological differential diagnosis between mucinous cystic neoplasm (MCN)

and non-neoplastic pancreatic cysts such as lymphoepithelial cyst and epidermoid cyst may not be

straightforward because imaging findings overlap.

Key Words : Pancreas, Cystic lesion, Radiological diagnosis
