Delayed Presentation of Right-Sided Diaphragmatic Hernia after Mechanical Ventilation in A Newborn with Hyaline Membrane Disease: A Case Report

Delayed presentation of right-sided diaphragmatic hernia occurred after the improvement of hyaline membrane disease in a male newborn. He presented with respiratory distress during the first few hours of life and had hyaline membrane disease confirmed by chest roentgenogram. After initial improvement with antibiotic therapy and ventilatory support for 2 weeks, sudden deterioration of respiration occurred and subsequent chest roentgenogram revealed herniated viscera in the right hemi-thorax. Two days ago his chest roentgenogram was normal. He did not have any other causes for diaphragmatic hernia such as group B streptococcal infection or necrotizing enterocolitis. To our knowledge, this association has not been previously reported in newborns.
