The cardiac silhouette is enlarged . There is widening of the mediastinum which may relate to prominent vasculature ; however , aortic or other mediastinal injury is not entirely excluded . If there is clinical concern for such , consider chest CTA . There is a linear left base opacity most likely represents atelectasis , although a component of aspiration is not excluded . There is central pulmonary vascular engorgement . No large pleural effusion is seen . There is no evidence of pneumothorax . No displaced fracture is seen .
    OUTPUT:
    
1 . Enlarged cardiomediastinal silhouette . If there is concern for acute aortic or other mediastinal process , consider chest CTA . Central pulmonary vascular engorgement . 2 . Likely left base atelectasis , although aspiration not excluded .
