Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heart size remains mildly enlarged . The mediastinal and hilar contours are similar . Pulmonary vasculature is not engorged . Right - sided calcified pleural plaques again may reflect the sequela of prior infection or hemothorax , unchanged , and somewhat limits assessment of the underlying pulmonary parenchyma . Streaky right basilar opacity could reflect atelectasis . Small right pleural effusion is new in the interval with fluid noted in the minor fissure . No pneumothorax is identified . There are no acute osseous abnormalities .
    OUTPUT:
    
1 . Assessment of the right lung parenchyma is limited by the presence of calcified pleural plaques , as seen previously , and may be the sequela prior infection or hemothorax . 2 . Streaky right basilar opacity could reflect atelectasis but infection is not excluded . Small right pleural effusion .
