    INPUT: Single frontal image of the chest again demonstrates large right upper lobe and right middle lobe masses , consistent with multiple previous chest studies and known history of metastatic melanoma to the lungs . There has been interval development of right upper lobe and right lower lobe hazy opacities , which could represent atelectasis or layering pleural effusion ; however , in the appropriate clinical context , a developing pneumonia can not be excluded . The left lung is again seen to be clear with no pleural effusion on the left . The cardiomediastinal silhouette appears to be unchanged , but visualization is limited due to adjacent right lung opacities .
    OUTPUT:
