title: Intrapancreatic accessory spleen issues: diagnostic and therapeutic challenges.
abstract: BACKGROUND
  Intrapancreatic accessory spleen is an exceptionally rare entity, commonly mistaken for a pancreatic neoplasm. Preoperative diagnosis based on radiologic imaging features is difficult. Aspiration cytology may be misleading due to poor sampling.
  
  
  METHODS
  We report a very rare case of an intrapancreatic accessory spleen which radiologically and cytologically mimicked a neuroendocrine pancreatic tumor.
  
  
  CONCLUSIONS
  Modern imaging techniques will probably lead to an increasing number of intrapancreatic accessory spleens being discovered, posing significant diagnostic and therapeutic challenges.
