    INPUT: PA and lateral chest views were obtained with patient in upright position . Comparison is made with the next preceding similar study of ___ . Mild - to - moderate cardiac enlargement persists and is unchanged . The same holds for the moderately widened and somewhat elongated thoracic aorta . Pulmonary vasculature is not congested and no acute new pulmonary infiltrates are seen . As the patient is status post lower lobe wedge resection and mediastinal exploration , the presence of the previously described three fiducial markers in left - sided perihilar position are again noted and additional peripheral markers relate to the area of left lower lobe wedge resection . No new abnormalities have developed and the post-operatively seen local pleural thickenings along the lower left lateral chest wall and running suture lines in the diaphragmatic surface have decreased in size indicating scar formation . A mild local elevation of the left - sided hemidiaphragm at the area of the biopsy persists .
    OUTPUT:
    
Satisfactory regression of post-operative left - sided lower lung changes related to wedge resection .
