Lungs are otherwise clear without a focal consolidation convincing for pneumonia . Heart size is upper limits of normal . There is no evidence of pulmonary edema . No pleural effusion . There is no pneumothorax . Surgical clips project over the left upper outer chest .
    OUTPUT:
    
Hyperinflated lungs . Focal opacity at the left lung base laterally on the frontal view , potentially pleural - based . Correlation with older films to document stability suggested and if not possible , chest CT is advised for further evaluation on a nonurgent basis .
