Ultrasound diagnosis: ‘Double bubble’ sign as a result of an enlarged stomach and duodenal cap. Usually found >24 weeks’ gestation. Polyhydramnios >24 weeks’ gestation in 50% of cases. Associated abnormalities: Chromosomal defects, mainly trisomy 21, are found in 30% of cases.

If a double-bubble sign is seen on antenatal ultrasound (as in this case), it is important to demonstrate a connection between the two fluid-filled structures because foregut duplication cyst, as well as other abdominal cysts, may simulate the appearance of a double-bubble sign
We classified 36 retrospective cases of duodenal atresia/stenosis based on intestinal malrotation status, and evalu-ated the diagnostic performance of ultrasound/upper gastrointestinal contrast studies to locate atresia/stenosis and intestinal malrotation, as well as ultrasound for detecting additional anomalies such as annular pancreas.
