Perinatal ultrasound may be the first diagnostic test in the assessment of the disorder. Polyhydramnios along with the classic finding double bubble reflecting a dilated proximal duodenum and stomach are virtually pathognomonic for the diagnosis. It is one of the most common anomalies in newborns, and represents almost half of all cases of neonatal intestinal obstruction. This is an anomaly that responds well to surgical treatment. We report a case of a patient hospitalized for threatened preterm labour at 8 months of pregnancy in whom duodenal atresia was suspected in a twin on ultrasound and confirmed after delivery.
