Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Compared with the prior chest x-ray , the left pigtail catheter is no longer visualized . No convincing pneumothorax is identified . Again seen are fractures along the left chest wall . Linear opacity seen adjacent to the left chest wall in left mid lung , related to the original site of the catheter , is again noted . There is faint , somewhat rounded opacity in this area which is new and could reflect some local contusion or hemorrhage , measuring roughly ___ .6 mm in diameter . Bibasilar atelectasis is again noted . The hazy component previously seen at the right base is less pronounced . No CHF or frank consolidation is identified . Minimal blunting of both costophrenic angles , without gross effusion . Probable background COPD . The cardiomediastinal silhouette is unchanged . New linear wirelike density likely represents an epidural catheter .
    OUTPUT:
    
1 . Left pigtail catheter no longer visualized . No pneumothorax detected . 2 . New focal somewhat rounded opacity in the left mid chest laterally -- question new hemorrhage or contusion at the previous site of the catheter . Attention to this area on followup films is requested . 3 . New epidural catheter noted --___ correlation is requested . 4 . Otherwise , I doubt significant interval change .
