    INPUT: The patient is status post coronary artery bypass graft surgery . The heart appears mildly enlarged . The cardiac , mediastinal and hilar contours appear unchanged . There is a moderate left - sided pleural effusion , probably with some degree of loculation along the left lateral hemithorax , as well as patchy parenchymal opacity , most likely compatible with atelectasis . On the right , there is also a pleural effusion , probably free - flowing and small to moderate in size . There is also a small pneumothorax on the right . The distance between the apical visceral pleural edge and the outer chest wall measures about 2 .2 cm . A mild interstitial abnormality suggests mild pulmonary edema . Fissures are thickened . The bones are probably demineralized .
    OUTPUT:
    
Pneumothorax on the right . Bilateral pleural effusions . Interstitial abnormality suggesting mild pulmonary edema . Although opacities at the lung bases , greater on the left than right , are probably compatible with atelectasis , underlying infectious process is not entiredly excluded by this examination .
