Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lungs remain hyperinflated . Increased interstitial markings bilaterally likely due to combination of chronic lung disease and mild interstitial edema . There are small bilateral pleural effusions with overlying atelectasis . Right base opacity may be due to combination of pleural effusion and atelectasis , but consolidation due to infection , aspiration , or pulmonary contusion not entirely excluded . No evidence of pneumothorax is seen . Biapical pleural thickening is again seen . The cardiac and mediastinal silhouettes are stable . Persistent loss of height of the mid to lower thoracic vertebral body . Fracture of a mid posterior right rib , possibly the posterior right sixth rib is of indeterminate age , but appears new since the prior study . Diffuse osteopenia .
    OUTPUT:
    
Diffuse osteopenia . Fracture of at least ___ mid posterior right - sided rib , possibly sixth rib of indeterminate age , but appears new since ___ . Additional rib fractures are difficult to exclude if high clinical concern for acute rib fractures , CT is more sensitive and should be considered . Small bilateral pleural effusion with overlying atelectasis . Right base opacity may be due to combination of pleural effusion and atelectasis , but underlying consolidation not excluded . Increased interstitial markings bilaterally likely combination of chronic lung disease and mild interstitial edema .
