Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Known heterogeneous consolidation in the left mid lung is not well seen on this single frontal view . Additional known nodules are also not well characterized on this radiographic examination . Linear opacities in the lung bases are similar compared to prior and likely reflect subsegmental atelectasis . No overt pulmonary edema is identified . Increased attenuation in the right mid-lung could reflect pneumonia or asymmetric pulmonary edema . Mild blunting of the bilateral costophrenic angles is unchanged and possibly due to small effusions or chronic pleural thickening . Cardiomediastinal and hilar contours are within normal limits .
    OUTPUT:
    
1 . Incompletely characterized known pulmonary nodules concerning for malignancy . 2 . Unchanged subsegmental basilar atelectasis and possible small bilateral pleural effusions . 3 . Increased opacity in the right mid lung may reflect pneumonia or possibly asymmetric pulmonary edema .
