Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The Port can be followed at least as far as the cavoatrial junction although more distally the exact termination point is not clear due to underpenetration . A right - sided PICC line terminates in the right brachiocephalic vein . Lung volumes are low . Cardiac , mediastinal and hilar contours appear within normal limits . There is a small to moderate pleural effusion on the right . It is difficult to exclude a small pleural effusion on the left . Otherwise , aside from suspected coinciding atelectasis at the right lung base , the lungs appear clear within limitations of technique .
    OUTPUT:
    
Right pleural effusion with associated atelectasis . Port - A - Cath difficult to delineate but it can be followed at least as far as the cavoatrial junction . PICC line terminating in the right brachiocephalic vein .
