Paraesophageal hernia in the neonatal period: suspicion on chest X-ray.

The paraesophageal hernia is rarely seen in the neonatal period. Presentation in neonatal period can be confused with the possibility of esophageal atresia or esophageal web. The upper gastrointestinal tract contrast study is diagnostic in this disease, but careful viewing of the plain X-ray of the chest can also lead to suspicion of the diagnosis. Two neonates with para-esophageal hernia are reported, one with the mesenterico-axial volvulus and the second neonate without volvulus.
