On the 8 hours radiograph, there is interval placement of chest tube on the left side with nearly complete resolution of the pneumothorax. Diffuse branching radiolucencies now evident, after the re-expansion of the left lung, representing pulmonary interstitial emphysema, which is the underlying cause for the previously seen pneumothorax. In addition, the right lung is less expanded with dramatic decrease in the branching radiolucencies through the right lung. Bilateral patchy hazy opacification related to respiratory stress syndrome is also evident.
