Pancreatic cystic lesions are uncommon and most are detected incidentally. They can be categorised into inflammatory and non-inflammatory or non-neoplastic and neoplastic. Inflammatory pancreatic cyst, pseudocysts occur in association with pancreatitis. Non-inflammatory cysts can be non-neoplastic or neoplastic. Cystic neoplasms include serous cystadenoma, mucinous cystic neoplasms, intraductal papillary mucinous neoplasms and solid pseudopapillary neoplasms. Cystic neoplasms, with the exception of the serous variant have malignant potential and need to be evaluated and followed up. Imaging represent an important part of the evaluation. Most lesions are small to moderate upon detection and large or giant lesions are rare. We report the case of a 43-year-old lady who presented with a giant mucinous cystic lesion and discuss on cystic lesions of the pancreas and the imaging features that may help to differentiate these lesions.
