    INPUT: Single upright AP image of the chest . The lungs are well expanded . There is opacity at the left lung base which is supsicious for pneumonia . There is pleural thickening at the left lung base , which could represent loculated pleural effusion . There is also diffuse left - sided pleural thickening with overall volume loss , which maybe related to previous infection or hemothorax . There is no right pleural effusion or pneumothorax . The cardiomediastinal silhouette is mildly enlarged . Destruction and sclerosis of both glenohumeral joints is noted , suggestive of possible rheumatoid arthritis .
    OUTPUT:
