Pancreatic Neuroendocrine Tumors (PNETs) are rare, reported to account for less than 1-2% of all pancreatic tumors. This, however, is likely an underestimation, as improved radiologic techniques and heightened awareness have resulted in an increase in the detection of incidentalomas, with estimations of true prevalence as high as 10%. The term “PNET” is an umbrella name encompasses a heterogenous group of neoplasms each with distinct clinical presentations, diagnostic radiographic features, management principles, and tumor/patient outcomes. In this context, accurate diagnosis is challenging, and management guidelines unclear. A high degree of clinical suspicion is required for best patient management. This manuscript provides a comprehensive of PNETs in the 21st century, in which we review the terminology, epidemiology classification, aetiopathogenesis, radiographic and histopathologic diagnostic features, management for localized and metastatic disease, as well as a review of features defining functional and non-functional PNETS, and finally describe prognostic features.
