    INPUT: As compared to the prior examination , there has been interval decrease in right - sided pleural effusion . A drainage catheter at the right base remains in position . No new focal consolidation is seen . A previously seen nodule in the right mid lung , measuring at least 3 cm is unchanged to minimally improved . The heart size is top normal . There is dense calcification and tortuosity of the thoracic aorta . There are severe bilateral degenerative changes of the acromioclavicular and glenohumeral joints .
    OUTPUT:
    
Interval drainage of right pleural effusion . A persistent nodule which appears fissural on prior CT examinations could represent loculated fluid ( pseudotumor ) or solid lesion . Though this lesion had increased in size on the prior two studies , this increase could be due to the recent effusion . After complete drainage of effusion , a repeat CT could be performed to see if the lesion has returned to its previous size .
