CXR AP at 1 day of life (above) shows bilateral symmetrical ground glass opacities throughout the lungs which have low lung volumes. CXR AP obtained at 30 days of life (middle) shows prominent bilateral interstitial fibrosis with cystic interstitial changes throughout the lungs which have increased lung volumes. CXR AP obtained at 90 days of life (below) shows faint bilateral interstitial fibrosis with cystic interstitial changes throughout the lungs which have even more increased lung volumes.
