    INPUT: A Port - A - Cath terminates at the cavoatrial junction . The heart is normal in size . The mediastinal and hilar contours appear unchanged . It is difficult to evaluate opacities seen on prior chest CT since these were radiographically occult . There are streaky left basilar opacities on this examination , not specific but suggesting minor atelectasis with a suspected very small new left - sided pleural effusion . The right lung remains clear by radiography . There is no pneumothorax or right - sided pleural effusion .
    OUTPUT:
    
Increasing patchy left basilar opacity , streaky and suggestive of atelectasis , with a small new left - sided pleural effusion .
