    INPUT: Right Port - A - Cath terminates at upper right atrium / cavoatrial junction . Bilateral multiple pulmonary nodular opacities reflect metastatic disease to the lungs and if any of its component is represented by lung infection or not , is very difficult to determine based on the chest radiograph alone . Heart size , mediastinal and hilar contours are normal . There is no bilateral pleural effusion .
    OUTPUT:
    
Bilateral multiple nodular opacities , left side more than right , may reflect pre-existing nodular metastatic disease , better assessed on the CT torso study dated ___ and if any of the opacities represent lung infection , is very difficult to determine based on the chest x-ray alone . Appropriate treatment with followup radiographs will be helpful to assess for the interval changes if clinical concern for infection persists .
