The cardiomediastinal silhouette is slightly prominent . The right hemidiaphragm is elevated , similar prior . There is increased retrocardiac density , consistent with left lower lobe collapse and / or consolidation , and a probable small left effusion . Pleural fluid is seen tracking along the right chest wall into the right lung apex . There is upper zone redistribution . Allowing for low inspiratory volumes , no definite CHF , though thickening of the minor fissure is noted .
    OUTPUT:
    
No pneumothorax detected . If there is high concern for a small pneumothorax , then a lateral view may help for further assessment . Left lower lobe collapse and / or consolidation and small bilateral effusions . Vascular plethora , without overt CHF .
