Congenital High Airway Obstruction Syndrome presenting as Nonimmune Hydrops in a 19-week Fetus

Abstract

Abstract A 27-year-old primigravida at 19 weeks of gestation with suspected hydrops fetalis. There were characteristic ultrasonographic features like hyper inflated and enlarged lungs, flattened diaphragm, small centrally displaced heart, and hydrops suggestive of CHAOS. Congenital high airway obstruction syndrome is a rare fetal anomaly causing nonimmune hydrops. Prenatal ultrasound features are characteristic. Meticulous system wise fetal imaging in the presence of hydrops would help in early diagnosis of the condition, helping in appropriate management of pregnancy.
