Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral chest views were obtained with patient in upright position . Comparison is made with the next preceding portable AP chest examination ___ ___ . Right - sided diaphragmatic elevation persists and appears unchanged . Significant cardiac enlargement as before . Configuration includes prominence of main pulmonary artery and consistent with previously diagnosed pulmonary hypertension . We on previous portable chest examination suspected right - sided pleural effusion with blunted right - sided lateral pleural sinuses confirmed as the present lateral view demonstrates rather extensive pleural densities reaching into the posterior pleural sinus . The left - sided pleural space remains free . There is no evidence of any pneumothorax in the apical area on either side . Comparison with the PA and lateral chest examination of ___ . The at that time existing pulmonary congestive vascular pattern does not exist anymore .
    OUTPUT:
    
Persistent right - sided diaphragmatic elevation with evidence of pleural effusion . As recommended on previous portable chest examination , a decubitus film may be helpful to assess more precisely the magnitude of pleural effusion and reveal possible right lower lobe atelectasis or infiltrate .
