Persistent low lung volumes and crowding on repeat upright chest radiograph. Hazy opacity at the periphery of the right base, which could be artifact or underlying contusion not excluded. Cardiac silhouette is within normal limits. Persistent mild prominence of the superior mediastinum, likely due to low lung volumes. If trauma mechanism suggests potential for underlying vascular injury, repeat PA and lateral chest radiograph is recommended. No displaced rib fractures identified.
