    INPUT: A right PICC is unchanged in position with the tip terminating in the low SVC . The inspiratory lung volumes remain low and slightly decreased from the most recent prior study . Bibasilar atelectasis and small pleural effusions are unchanged . No pneumothorax is detected , although irregular vertically oriented linear densities project over the right hemithorax , which likely represent material external to the patient . Mild pulmonary vascular congestion is stable . The cardiac silhouette is mildly enlarged but unchanged . The mediastinal contours are within normal limits with mild tortuosity of the thoracic aorta and calcification of the aortic arch . The left hilus appears prominent , which is unchanged from the prior study . The visualized upper abdomen is unremarkable . Moderate to severe degenerative change is noted in the right shoulder joint .
    OUTPUT:
    
1 . No pneumothorax . 2 . Stable appearance of the chest with mild vascular congestion and small bilateral pleural effusions on the left greater than the right with underlying atelectasis . 3 . Right shoulder osteoarthritis .
