title: Pseudo double bubble: jejunal duplication mimicking duodenal atresia on prenatal ultrasound.
abstract: Prenatal ultrasound showing a double bubble is considered to be pathognomonic of duodenal atresia. We recently encountered an infant with prenatal findings suggestive of duodenal atresia with a normal karyotype who actually had a jejunal duplication cyst on exploration. A finding of an antenatal double bubble should lead to a thorough evaluation of the gastrointestinal tract and appropriate prenatal/neonatal testing and management as many cystic lesions within the abdomen can present with this prenatal finding.
