    INPUT: Assessment is somewhat limited by patient rotation . Left - sided pacemaker device is re - demonstrated with leads terminating in the regions of the right atrium and right ventricle . Previously noted marked diffuse dilatation of the esophagus may be somewhat improved , but not fully assessed on this single view . Marked enlargement of the right hilum as well as fullness of the right mediastinal contour reflects known lymphadenopathy , unchanged . Mild to moderate pulmonary vascular congestion is noted with perihilar haziness and vascular indistinctness . Opacification within the right lung base is worse compared to the previous radiograph , concerning for collapse . Known nodule within the right middle lobe is better assessed on the previous CT . There is a moderate size right pleural effusion . Elevation of the left hemidiaphragm is chronic . No pneumothorax is demonstrated .
    OUTPUT:
    
1 . Mild to moderate pulmonary edema . 2 . Worsening opacification of the right lung base compared to the previous chest radiograph concerning for collapse though infection can not be excluded . Known right middle lobe nodule is not well assessed on this single view . 3 . Marked diffuse dilatation of the esophagus compatible with achalasia is not well assessed on the current exam . 4 . Moderate size right pleural effusion , increased in size compared to the previous study . 5 . Continued right hilar and mediastinal lymphadenopathy .
