Pancreatic endocrine tumors are rare neoplasms. It is important to distinguish them from the more common ductal adenocarcinoma of the pancreas because they are slowly progressive and specific treatments are available. The CT findings of pancreatic endocrine tumors usually vary according to the functioning or nonfunction-ing status. In this article, the authors illustrate typical and atypical CT findings of pancreatic endocrine tumors with radiopathologic correlations and give examples of other pancreatic conditions mimicking pancreatic endocrine tumors.
Pancreatic endocrine tumors manifest a wide variety of clinical and radiologic appearances. They are conveniently divided on clinical grounds into those that are functioning and those that are clinically silent (1). In this article, we illustrate various patterns on the different helical CT phases with a special focus on the lesion enhancement and local signs of invasion, and give examples of other pancreatic conditions mimicking pancreatic endocrine tumors.
