title: Duodenal duplication cyst in a 52-year-old man: A challenging diagnosis and management.
abstract: BACKGROUND
  Duodenal duplication is a rare congenital malformation. Although more frequent in childhood, it may rarely be observed in adulthood. Pre-operative diagnosis can be difficult.
  
  
  METHODS
  We report the case of a 52-year-old man with a duodenal duplication cyst, who was misdiagnosed even after a primary surgery. Definitive treatment needed an extensive diagnostic workup and a second delicate operation.
  
  
  CONCLUSIONS
  This article discusses the incidence of duodenal duplications, their types, their clinical presentations, the radiologic and diagnostic features along with different therapeutic options.
  
  
  CONCLUSIONS
  Duodenal duplication should always be one of the differential diagnoses proposed when approaching upper abdominal cystic formations.
