Lung ultrasonographic findings in a newborn with neonatal meconium aspiration syndrome (MAS). The newborn was delivered at 39⁺⁵ weeks of gestation and presented with meconium staining of the amniotic fluid, asphyxia at birth, and difficulty breathing after resuscitation. Lung ultrasonography showed large areas of pulmonary consolidation with air bronchogram and irregular edges in the lungs, especially in the right lung. The pleural line was abnormal, and the A-line disappeared in the consolidation area. Chest X-ray showed patchy and cloudy shadows that were consistent with MAS.
