What are common X-ray findings in RDS?

In the context of Respiratory Distress Syndrome (RDS) in neonates, the correct choice highlights the characteristic X-ray findings associated with the condition. RDS is primarily caused by insufficient surfactant in the lungs, leading to collapse of the alveoli and ultimately impaired gas exchange.

The reticulo-granular pattern, also referred to as a "ground-glass" appearance, is indicative of the hazy opacification seen on chest X-rays in infants with RDS. This pattern results from the development of atelectasis and the accumulation of fluid in the alveolar spaces, which is a direct consequence of inadequate surfactant production. The reduced lung volumes reflect the inability of the alveoli to inflate properly due to the presence of atelectasis.

In contrast, other findings such as increased lung volumes and air bronchograms are more often associated with conditions such as bronchopulmonary dysplasia or meconium aspiration syndrome. Hazy opacification can occur in various pulmonary conditions, but the specific combination of reticulo-granular patterns and reduced lung volumes is distinctively connected to RDS. The sunburst pattern and blunting of angles are not typical for RDS and may suggest other pathologies.
