    INPUT: The tip of a right pectoral MediPort projects over the lower SVC . There is no pneumothorax . Bilateral coarse reticular nodular opacities have slightly increased at the left lung base . The presence of chronic fibrotic lung disease makes it difficult to exclude small pulmonary metastases . Correlation with cross - sectional imaging if not already obtained would be helpful . A right upper quadrant stent is again noted . A radiopaque object with both rounded and triangular components projecting over the right lung base is likely external to the patient .
    OUTPUT:
    
Slight interval increase in heterogeneous opacities at the left lung base , which may be due to developing infection . The presence of chronic fibrotic lung disease makes it difficult to exclude small pulmonary metastases . Correlation with cross - sectional imaging would be helpful .
