Congenital high airway obstruction syndrome (CHAOS) combined with esophageal atresia, tracheoesophageal fistula and duodenal atresia

Here we report a very rare case of prenatally diagnosed CHAOS (laryngeal atresia) complicated with esophageal atresia, tracheoesophageal fistula (TEF) and duodenal atresia, and the patient was saved by EXIT. This combination of anomalies resulted in a very confusing prenatal diagnosis with unique imaging feature of the fetus.
