Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient is rotated significantly to the left , limiting evaluation . There is blunting of the posterior costophrenic angles and obscuration of the left hemidiaphragm , suggesting small to moderate pleural effusion ( s ) . Left base opacity may be due to combination of pleural effusion and atelectasis as well as overlying external structure , however , underlying consolidation is not excluded . There is mild increase of the interstitial markings bilaterally raising concern for mild interstitial edema . The mediastinum is difficult to assess . Cardiac silhouette is also difficult to assess but is likely top - normal to mildly enlarged . Chronic deformity of the proximal right humerus is seen .
    OUTPUT:
    
Limited study due to the patient being severely rotated as well as patient 's arm overlying the lateral view . Given this , left base opacity with blunting of the posterior costophrenic angles , concerning for small to moderate pleural effusion ( s ) with atelectasis , underlying left base consolidation not excluded . Possible mild interstitial edema . Difficult to assess the heart and mediastinum . The cardiac silhouette is likely top - normal to mildly enlarged .
