Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low . This accentuates the size of the cardiac silhouette which is mildly enlarged . Mediastinal and hilar contours are within normal limits . Pulmonary vasculature is not engorged though there is crowding of the bronchovascular structures . Small to moderate right pleural effusion is demonstrated with streaky bibasilar airspace opacities , likely atelectasis though superimposed on the patient 's known chronic interstitial lung disease . 2 .2 cm focal opacity is seen projecting over the right upper lobe , which was previously noted to be appear as a more vague opacity on the prior exam . No pneumothorax is identified . No acute osseous abnormality is visualized .
    OUTPUT:
    
1 . 2 .2 cm focal opacity projecting within the right upper lobe which may reflect a more confluent area of chronic interstitial lung disease / fibrosis as a vague opacity was demonstrated in this region on the previous chest radiograph . Further assessment with chest CT is suggested . 2 . Small to moderate size right pleural effusion with streaky bibasilar atelectasis likely superimposed on the patient 's known chronic interstitial lung disease .
