Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lung volumes are low and the patient 's chin overlies the medial lung apices , obscuring the view . New opacities are seen overlying the mid to upper left lung . Streaky opacities at the lung bases bilaterally are likely secondary to atelectasis . Mild to moderate cardiomegaly is persistent . Aorta is tortuous and calcified , however the hilar and mediastinal contours are otherwise unremarkable . Persistent blunting of bilateral costophrenic angles which coudl be due to persistent trace effusions . There is no evidence of a pneumothorax .
    OUTPUT:
    
New left lung opacities are concerning for pneumonia . Streaky bibasilar opacities are likely secondary to atelectasis , however an acute infectious process can not be excluded at those locations as well .
