Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There has been interval placement of a Dobbhoff tube which projects over the trachea and appears to enter the left mainstem bronchus in course inferiorly , presumably penetrating the diaphragm and with distal tip projecting over the mid left abdomen . There is a large left pneumothorax with rightward shift of mediastinal structures . There is stable position of right - sided port with distal tip projecting over cavoatrial junction . Allowing for changes due to mediastinal shift , the cardiomediastinal silhouette is unchanged . The bilateral hila are not well visualized . The left lung is collapsed against the left mediastinum secondary to large pneumothorax . The right lung is clear without evidence of focal consolidation . There is no right pneumothorax . There are no pleural effusions .
    OUTPUT:
    
1 . New large left pneumothorax with rightward mediastinal shift . 2 . Dobbhoff tube appearing to enter trachea and left mainstem bronchus , with diaphragmatic penetration and distal tip projecting over the left mid abdomen .
