Learning objectives We propose a comprehensive imaging analysis, reporting and follow-up of pancreatic cystic lesions (PCL).
Read more Background PCL affect 10% of the general population and increase with age [1,2]. With improved imaging resolution, this prevalence is even higher [3].The spectrum of these lesions varies between non-neoplasic, benign and malignant neoplasms. They consist of pancreatic pseudocysts and epithelial cystic neoplasms, including serous cystadenoma (SC), intraductal papillary mucinous neoplasm (IPMN), and mucinous cystic neoplasms. The two latter present a malignant potential. Determining whether a PCL is mucinous or non-mucinous and benign or malignant are two questions for an appropriate...
Read more Findings and procedure details PCLs are commonly divided in three types: pseudocyst or encapsulated necrosis (EN), common cystic neoplasm (CN) and rare CN (figure 1).Pseudocysts or (EN) are associated with pancreatitis or history of abdominal trauma.Pseudocyst is a peripancreatic collection, often with a round shape and homogeneous content (water density). Some debris can be found, mostly on MRI. There is an enhanced, sometimes thick, pseudocapsule. Pseudocyst may communicate with the pancreatic ductal system but is never located within the pancreas (figure 2).EN can be...
Read more Conclusion Cystic lesions of the pancreas are common. Appropriate analysis of the radiological features is essential for diagnosis or to narrow the differential diagnosis and allow optimal care and follow-up.
