A Case with Duodenal Duplication Cyst: Prenatal Diagnosis and Surgical Management

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