The “double bubble” sign is a common sign of congenital duodenal obstruction (CDO), which has been detected during prenatal diagnosis for over 40 years. CDO is strongly associated with chromosomal and structural abnormalities and encompasses a wide spectrum of diagnoses. Here, we describe a case of duodenal stenosis, a rare cause of duodenal obstruction, which was suspected using conventional two-dimensional ultrasound and three-dimensional reconstruction with the HDlive silhouette mode at the 28th prenatal week. The suspicion was further supported by magnetic resonance imaging performed at the 32nd prenatal week and confirmed by postnatal surgery.
