    INPUT: Frontal and lateral views of the chest were obtained . A right - sided Port - A - Cath is seen , terminating in the right atrium . Innumerable bilateral pulmonary nodules are again seen , given differences in technique , without significant interval change . No pleural effusion or pneumothorax is seen . The cardiac and mediastinal silhouettes are stable . No evidence of free air is seen beneath the diaphragms .
    OUTPUT:
    
Minimal bilateral nodular opacities again left greater than right , likely metastatic disease , better assessed on previous CTs , difficult to assess whether any these opacities represent lung infection on chest x-ray alone .
