Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A pigtail catheter projects over the right mid upper hemithorax and another projects over the left lower hemithorax , unchanged in position overall . Tiny right apical pneumothorax without evidence of tension has perhaps decreased in size , but is not larger and has been replaced in part by fluid . Large right pleural effusion with severe atelectasis has decreased since yesterday but is still substantial . The heart size can not be adequately assessed , but is probably moderately enlarged and overall unchanged . No appreciable left pleural effusion . Lung volumes remain low . No left pneumothorax . Interval decrease in left edema . The possibility of lymphangitic spread can not be excluded given the clinical history . Prominence of the right hilar region may reflect lymphadenopathy given history of metastatic cancer and recent CTA .
    OUTPUT:
    
Persistent but improved large right pleural effusion and small right pneumothorax and left edema vs lymphangitic spread .
