The “double bubble” sign is an ultrasonographic finding that is characterized by the presence of a double liquid-filled bubble image in the fetal abdomen. It indicates duodenal atresia which is frequently associated with other congenital anomalies including esophageal atresia. Antenatal ultrasound diagnosis may sometimes miss this association leading to postnatal surprise and insufficient care. We report the case of a double fetal bubble image identified during a routine antenatal assessment, initially diagnosed as a simple duodenal atresia, with postnatal discovery of an association with esophageal atresia which was overlooked.
