    INPUT: A tracheostomy tube is in place . The patient is status post median sternotomy . A right pleural pigtail catheter again projects over the right costophrenic angle . A left PICC is unchanged in position with the tip terminating in the upper to mid SVC . A right PICC is again noted with the tip terminating at the level of the right axilla . There is no definitive evidence of pneumothorax . There is slightly increased opacification of the left lung base likely reflecting a combination of moderate left pleural effusion and underlying atelectasis or consolidation . Right basilar atelectasis is slightly improved from the most recent prior study . Enlargement of the cardiac mediastinal silhouette is unchanged . Calcification of the aortic knob and descending thoracic aorta is re - demonstrated .
    OUTPUT:
    
1 . No definitive pneumothorax . 2 . Right PICC terminating at the level of the right axilla , as before . 3 . Slightly increased moderate left pleural effusion and underlying atelectasis or consolidation . 4 . Improved right basilar atelectasis .
