    INPUT: There is a Port - A - Cath terminating in the cavoatrial junction . The heart is at the upper limits of normal size . The mediastinal and hilar contours appear unchanged . There is mild central pulmonary vascular prominence as well as indistinctness in upper zone redistribution suggesting mild fluid overload . There is a nodular opacity projecting over the right lower lung . An additional one also projects near the site of a Port - A - Cath device in the right mid abdomen . The possibility that these may reflect metastatic disease should be considered .
    OUTPUT:
    
Findings suggesting mild fluid overload . New nodular densities projecting over the right lung for which a CT evaluation is suggested when clinically appropriate since these may represent new lung nodules in the setting of known prior malignancy .
