Relative to prior examination , prior central bronchovascular and diffuse interstitial prominence is less conspicuous compatible with improved pulmonary edema . Likely mild heart failure persists . A small right pleural effusion and likely left pleural effusion is present . Elevation of the left hemidiaphragm appears to have been present on radiograph dated ___ . Though this may reflect eventration of the hemidiaphragm , somewhat lateral displacement raises suspicion of a sub pulmonic effusion . Hilar and mediastinal contours are stable in appearance . Tortuous descending aorta is stable . No acute osseous abnormality is detected .
    OUTPUT:
    
Relative to prior study dated ___ , pulmonary edema is improved on a background of interstitial lung disease . Right pleural effusion and likely small left pleural effusion . Elevation of the right hemidiaphragm may reflect diaphragmatic eventration though question subpulmonic effusion .
