To review imaging features on CT and MRI of most common cystic lesions of the pancreas. To establish a diagnostic strategy allowing distinction between benign and malignant cystic lesions of the pancreas To be able to establish the follow up strategy for incidental cystic lesions of the pancreas

A retrospective case series study of 50 patients (twenty male and thirty female) with pancreatic cystic lesion recruited in the surgery and gastro-enterology wards within our institution. Given the fact that they were, pathologically, non-cystic lesions, pseudo cysts were excluded from our study.

1. Epidemiology: · Our study regroups: o 14 branch ducts or mixed intraductal papillary mucinous neoplasms cases (IPMN) o 6 mucinous cystadenomas (MCADm) and 4 mucinous cystadenocarcinomas (MCADc) o 8 serous cystadenomas(SCAD) o 7 solid pseudo papillary tumors (SPPT) o 2 Hydatic cysts of the pancreas o 2 Neuroendocrine tumors o 2 carcinosarcomas of the pancreas, 3 cystic adenocarcinomas of the pancreas, 1 cystic hemangioma and 1 multiple simple pancreatic cysts occurred on a patient presenting a Von Hippel Lindau syndrome · Patients were aged...

Cystic lesions of the pancreas have multiple imaging aspects, some of which are specific, allowing an easier diagnosis and therefore a better management. Among these lesions, the most challenging ones are definitely mucinous neoplasms and especially branch ducts IPMNs, which have raised a considerable amount of concern among scientific societies regarding the optimal assessment and treatment. Positive diagnosis for BD-IPMN is quiet easily performed on MRI, which allows the detection of small lesions, the assessment of pancreatic ducts communication and the identification of suggestive morphological...
