Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Cardiac silhouette size is mildly enlarged but unchanged . Aorta is mildly tortuous . Widening of the mediastinal contour and prominence of the right paratracheal stripe is compatible with underlying lymphadenopathy . Several scattered nodular opacities are noted within both lungs , most pronounced within the left upper lobe , not substantially changed from the prior radiograph . Suture material is again demonstrated within the right lower lobe with adjacent opacity likely reflecting a combination of postsurgical scarring and atelectasis . Blunting of the right costophrenic angle likely reflects a small pleural effusion , also unchanged . No new focal consolidation is seen . There are mild degenerative changes in the thoracic spine .
    OUTPUT:
    
Small right pleural effusion and right basilar opacity likely reflecting a combination of atelectasis and postsurgical scarring . Bilateral nodular opacities , similar compared to the prior radiograph , and better assessed on the prior CT . No new focal consolidation identified . Unchanged widened mediastinal contour compatible with lymphadenopathy .
