    INPUT: The pigtail chest tube terminates in the right mid lung . There has been interval resolution of prior pneumothorax . No pneumoperitoneum is evident on this portable examination . A chronic right lower lobe triangular opacity is likely related to persistent atelectasis . Subsegmental left lower lobe atelectasis is similar . Small bilateral pleural effusions are also likely . There is no overt interstitial edema . Lung volumes are low . Cardiomediastinal and hilar contours are within normal limits .
    OUTPUT:
    
1 . Right chest tube in expected position . Interval resolution of prior right pneumothorax . 2 . Low lung volumes with persistent basilar atelectasis and small effusions , similar to prior .
