bilateral interstitial opacities and central vascular prominence is stable compared to the prior study suggesting mild interstitial edema. posterior basilar opacity on the lateral view is grossly similar as compared to the study from <unk> and may represent atelectasis/scarring although infection is not excluded in the appropriate clinical setting. no definite fracture seen, although evaluation is not optimal for such. this study does not well assess the spine. if there is clinical concern for spine or rib fracture, dedicated imaging of the spine or ribs should be obtained.
