Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest are obtained . A left - sided Port - A - Cath is again seen , terminating at the distal SVC / cavoatrial junction . In the interval since the prior study , there has been development of left base opacity seen to represent combination of pleural effusion and atelectasis on subsequent CT along with worsening metastatic disease . At the lateral left lung base , there is a rounded 2 .3 x 1 .7 cm opacity concerning for additional pulmonary metastasis . Minimal right base opacity most likely represents atelectasis . There are multiple bilateral pulmonary nodules , better assessed on CT . Cardiac and mediastinal silhouettes are stable .
    OUTPUT:
    
1 . Left base opacity corresponds to moderate left pleural effusion with overlying atelectasis seen on subsequent chest CT . Rounded opacity at the lateral left base is worrisome for worsening metastasis . Bilateral pulmonary nodules , better assessed on CT .
