Cystic Pancreatic Lesions: A Review of Diagnosis and Management

Abstract

AbstractPancreatic cysts are commonly seen with increasing use of cross-sectional imaging. They range from a benign inflammatory process that can produce pseudocysts to malignant lesions such as mucinous cystadenocarcinoma. Other common pancreatic cysts include intraductal pancreatic mucinous neoplasms and serous cystadenomas. Optimized imaging protocol dedicated to imaging the pancreas is required, such as multiphasic computed tomography, magnetic resonance imaging/magnetic resonance cholangiopancreatography, or endoscopic ultrasound, to fully detect and characterize the lesions. A confident diagnosis can be made on imaging when features such as calcifications, pancreatic duct diameter, main duct communication, and mural nodules are assessed. Additionally, pathologic evaluation from fluid/tissue sampling aid in diagnosis. Optimal management of pancreatic cysts is achieved based on the imaging features, conveying key findings in the radiology report, pathologic evaluation, and clinical factors.
