The 'double bubble' sign in prenatal diagnosis is most often associated with duodenal atresia. However, other causes of upper intestinal obstruction and cystic abdominal masses need to be considered. One possible diagnosis that can mimic the 'double bubble' sign of duodenal atresia is duodenal duplication, but little information is available to guide sonologists in the prenatal diagnosis of this rare congenital anomaly. In this case report we describe the successful prenatal diagnosis of duodenal duplication, by relying on the early gestational age of presentation, the lack of polyhydramnios, the failure to consistently demonstrate a 'double bubble' on transverse images, and the presence of a normal distal bowel pattern.
产前诊断中的“双泡”征最常与十二指肠闭锁相关。然而，还需要考虑上消化道梗阻和腹部囊性肿块的其他病因。一种可能模仿十二指肠闭锁“双泡”征的诊断是十二指肠重复畸形，但关于这种罕见先天性异常的产前诊断，可供超声科医生参考的信息很少。在本病例报告中，我们描述了通过依赖早孕期就诊、无羊水过多、横断图像上未能持续显示“双泡”以及存在正常的远端肠管形态，成功进行十二指肠重复畸形的产前诊断。
