title: Choledochal cyst as a diagnostic pitfall: a case report.
abstract: BACKGROUND
  Choledochal cysts are rare congenital anomalies. Their diagnosis is difficult, particulary in adults.
  
  
  METHODS
  This case report demonstrates the diagnostic and therapeutic pitfalls.
  
  
  CONCLUSIONS
  To prevent cost-intensive and potentially life-threating complications, a choledochal cyst must be considered in the differential diagnosis whenever the rather common diagnosis of a hepatic cyst is considered.
