On clinical examination, RR > 60/min for > 2 hours, grunting, flaring of nasal alae, subcostal, intercostals retractions, diffuse reticulogranular pattern and air bronchogram on X-ray chest, arterial blood gas done whenever necessary was done and all preterms < 37 wks.
The presence of an air bronchogram and a decrease in lung sliding are other ultrasonographic findings in AAA (11).
The radiological evidence is the pulmonary edema with interstitial opacity, consolidations, air bronchogram, and Kerley's "B" lines.
Chest radiographs showed a severe bilateral air bronchogram in the lung field.
An additional finding that may help to confirm this diagnosis is the presence of the air bronchogram (Fig.
Radiographic features were recorded as either normal, presence of patchy opacities in one or more lobes, or lobar/segmental consolidation with or without an air bronchogram.
As shown in Table 2, the vast majority of the pulmonary infiltrates were considered as alveolar type, two-thirds had air bronchogram, one in three patients had pleural effusion, usually on one side, and one in four multilobar disease.
In some patients air bronchogram formation (28%), feeding vessel sign (67%), pleural effusion and empyema can be observed (3), (4).
At the time of admission, the chest CT showed diffuse exudation, uniform ground-glass shadow, which is more obvious in the right lung, visible air bronchogram sign in the right lower lobe of the lung.
5 cm heterogeneously enhancing mass lesion with compression of right upper lobe bronchus with consolidation with air bronchogram and cavitation noted in right upper lobe.
Infants with diffuse increased density, need for mechanical ventilation and respiratory acidosis according to blood gases were considered to have severe RDS, infants with pathcy areas of increased density on lung graphy and need for continuous positive airway pressure (CPCP) were considered to have moderate RDS and infants with scattered areas of increased density and/ or air bronchogram for whom mask oxygen support was sufficient and who had no respiratory acidosis according to blood gases were considered to have mild RDS.
