Duodenal duplication cyst in a 52-year-old man: A challenging diagnosis and management

Abstract

Introduction: 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.

Presentation of case: 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.

Discussion: This article discusses the incidence of duodenal duplications, their types, their clinical presentations, the radiologic and diagnostic features along with different therapeutic options.

Conclusion: Duodenal duplication should always be one of the differential diagnoses proposed when approaching upper abdominal cystic formations.
