Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There are low lung volumes . Increased interstitial markings bilaterally could be due to mild pulmonary edema and / or chronic lung disease . Left basilar opacity could be due to atelectasis although underlying consolidation is not excluded . Tracheobronchial tree calcifications are seen . Subtle opacity underlying the left mid lung could relate to underlying pulmonary contusion . There may also be a small left pleural effusion The cardiac silhouette is enlarged . The aorta is tortuous . The bones are diffusely osteopenic , limiting sensitivity for fractures however , there are multiple lateral left - sided rib fractures including at least the left third , fourth , fifth , seventh , possibly sixth . There are likely several compression deformities in the spine although not well assessed on this study .
    OUTPUT:
    
Multiple left - sided rib fractures involving at least the left third , fourth , fifth , seventh , and possibly sixth rib . Subtle opacity overlying the lateral left mid lung could relate to underlying pulmonary contusion . Possible small left pleural effusion .
