Congenital high airway obstruction syndrome (CHAOS) is a near fatal condition of multifactorial inheritance, due to the obstruction of the fetal upper airways, which may be partial or complete in which the fetus has a dilated trachea, enlarged echogenic lungs, an inverted or flattened diaphragm, and ascites. Prenatal recognition of the disease is quite important due to the recently described management options We report here a case of CHAOS due to laryngeal atresia diagnosed by antenatal ultrasonography at 19 weeks of gestation. We also briefly review the relevant literature with the associated management options. 1. Smith II, Bain AD.
