CXR of respiratory distress syndrome with symmetrical distribution of artificial surfactant in the lungs
Initial CXR AP (left) shows low lung volumes and symmetrical ground glass opacity in both lungs. CXR AP obtained 1 hour after the administration of artificial surfactant (right) shows increased lung expansion and clearing of the previously seen ground glass opacity in both lungs.

The diagnosis was respiratory distress syndrome showing the appearance of the chest before and after the symmetrical administration of artificial surfactant.
