Coexistence of Pancreatic Neuroendocrine Tumor and Pseudotumor: Two Rare Lesions

Abstract

Neuroendocrine tumors and pseudotumors of the pancreas are 2 separate rare lesions. Neuroendocrine tumors originate from neuroendocrine cells, but many different factors have been suggested for the origin of pseudotumors. As the first reports of these 2 distinct entities found in a single patient have been published, our aim is to present the imaging and pathological characteristics of these entities.
