title: A case with duodenal duplication cyst: prenatal diagnosis and surgical management.
abstract: OBJECTIVE
  We report the first case of a subhepatic cystic mass diagnosed in utero that subsequently proved to be a duodenal duplication cyst.
  
  
  METHODS
  Conventional prenatal abdominal ultrasound.
  
  
  RESULTS
  On prenatal ultrasonography, the differential diagnosis was choledochal cyst, bowel duplication cyst, or omental cyst.
  
  
  CONCLUSIONS
  The prenatal detection of a cystic mass allowed close neonatal surveillance and timely surgical intervention prior to the onset of potentially serious complications.
