Rare pancreatic masses: a pictorial review of radiological concepts

Abstract

Non-ductal pancreatic neoplasm (NPN) represents a heterogeneous group of pancreatic masses, in which diagnosis and management remain challenging due to their overall rarity. Knowledge of their radiologic features is essential for differential diagnosis and to guide clinical decisions for optimal management. The purpose of this paper was to present radiological patterns of these rare pancreatic tumors, solid or predominantly solid, with emphasis in the differential diagnosis and surgical management.
