    INPUT: Tracheostomy tube is in the midline , unchanged from prior . The right PICC line has been repositioned , looping in the internal jugular vein and terminating in the right brachiocephalic vein . Diffuse opacification in the right hemithorax is unchanged . The left mid lung opacity obscuring the left heart border is more prominent . This is partially due to the lung lesion seen on recent CT , but postobstructive pneumonia can not be ruled out . Small pleural effusion on the right is unchanged . No pneumothorax . The cardiomediastinal silhouette is stable .
    OUTPUT:
    
1 . Interval increase of the left mid lung opacification partially due to underlying lung lesion but postobstructive pneumonia can not be ruled out . 2 . Interval reposition of right PICC line looping in the right internal jugular vein and terminating in the right brachiocephalic vein
