    INPUT: Post - traumatic findings along the left posterolateral chest wall including pleural thickening appear unchanged . Again there is also a mild to moderate relative elevation of the right hemidiaphragm with a pleural effusion that is probably small to moderate in size on the right and possibly with a small pleural effusion on the left . Streaky left basilar opacity suggests atelectasis . Perihilar fullness and hazy prominent pulmonary vasculature suggest mild - to - moderate pulmonary vascular congestion .
    OUTPUT:
    
Findings most suggestive of congestive heart failure with parenchymal changes and suspected pleural effusions . Streaky left basilar opacity is most suggestive of atelectasis . Similar post - traumatic changes along the left chest wall .
