    INPUT: Patient 's overlying chin obscures the medial lung apices . There are low lung volumes . Small to moderate bilateral pleural effusions are seen . Left base opacity may be due to combination of pleural effusion and atelectasis although underlying consolidation is difficult to exclude . There is mild to moderate pulmonary edema . The cardiac silhouette appears mildly enlarged . Mediastinal contours are stable .
    OUTPUT:
    
Patient 's chin overlies the medial lung apices , partially obscuring the view . There are also low lung volumes . Given the above , there are small to moderate bilateral pleural effusions with overlying atelectasis . Left base opacity may be due to combination of pleural effusion and atelectasis , although underlying consolidation is not excluded . Moderate pulmonary edema . Mild cardiomegaly .
