Which radiographic findings may be seen with meconium aspiration?

Explanation:
Meconium aspiration injures the newborn lung through chemical irritation and airway obstruction, leading to inflammation and collapse of some airways with areas of air trapping elsewhere. This produces a chest x-ray pattern of patchy infiltrates along with atelectasis and hyperinflation. The combination of regions of collapse (atelectasis) and increased lucency from air trapping (hyperinflation) is characteristic of meconium aspiration. Other radiographs showing a completely clear lung, a normal chest, or a large pleural effusion do not reflect the typical MAS pattern.
