    INPUT: Right - sided chest tube terminates in unchanged position with tip projecting along the medial base of the right hemi thorax . Again demonstrated is a right hilar mass with hilar lymphadenopathy and multiple pleural - based masses compatible with metastases , better assessed on the previous CT . Fiducial markers are noted within the superior aspect of the left hilar mass as well as within the right upper lobe , unchanged . A moderate size right pleural effusion may be minimally increased in size compared to the prior study with worsening airspace opacification in the right lung base which may reflect worsening atelectasis , but infection is not excluded . No pneumothorax is identified . Apart from subsegmental atelectasis in the left lower lobe , the left lung is clear . The cardiac and mediastinal contours are unchanged with the heart size appearing within normal limits . Atherosclerotic calcifications are noted throughout the thoracic aorta .
    OUTPUT:
    
Worsening opacification in the right lung base which may reflect increased atelectasis , but infection is not excluded . Moderate size right pleural effusion also appears minimally increased from prior . Grossly unchanged appearance of right hilar mass and multiple pleural - based metastases . No pneumothorax .
