A tracheoesophageal fistula (TEF) is an abnormal connection between the esophagus and the trachea and is a rarely seen pathology. The absence of the fetal stomach or visualization of the fetal stomach smaller than normal by ultrasound in early gestation, and detection of polyhydramnios in third trimester are the most valuable signs in ultrasonographic examination. In addition to this, depending on the type of the anomaly, blind pouch sign of the esophagus can be detected at the mediastinum or in the neck, next to trachea. The rate of diagnosis in the ultrasonographic examination during pregnancy is about %42, and %58 of the patients diagnoses in postpartum period. In this paper we aimed to present a baby diagnosed TEF, as a rare entity.
