[Alterations of pulmonary patterns in roentgenographic follow up studies in respiratory distress of newborns and prematures (author's transl)].

The most common causes of respiratory distress in the newborn and the frequently rapidly changing pulmonary pattern in the follow up studies are presented. Various degrees of the hyaline membrane disease and bronchopulmonary dysplasia are demonstrated as well as the different changes of the pulmonary pattern in controlled and assisted ventilation, recurrent atelectasis, dystelectasis, emphysema, pneumothorax and pneumomediastinum. Chest film follow up series are demonstrated. The differential diagnosis includes pulmonary aspiration syndrome, the neonatal pneumonia and emergency cases in pediatric surgery (here an example of a congenital diaphragmatic hernia).
