Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac , mediastinal and hilar contours appear unchanged . There is somewhat increased opacification of the right costophrenic sulcus with elevation and flattening which may reflect scarring or atelectasis associated with a small persistent pleural effusion , but this appearance is unlikely to reflect an acute process . To some extent , this opacification was present on the prior examination , although less prominent . There is no evidence for pleural effusion on the left . There is no pneumothorax . A patchy focal opacity projecting over the right upper lobe suggests minor scarring which is unchanged . An oval nodular focus projecting over the left lower lung probably is due to a nipple shadow .
    OUTPUT:
    
1 . No definite evidence of acute disease . 2 . Blunting of the right costophrenic sulcus , more prominent , probably a chronic finding . 3 . Oval nodular focus suggesting a nipple shadow projecting over the left side , although hard to confirm since it was not visible on the prior study . When clinically appropriate evaluation with an additional PA view using nipple markers is suggested . Findings and recommendations discussed with Dr . ___ on ___ , at 2 pm by telephone .
