Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A left PICC is unchanged in position with the tip terminating at the cavoatrial junction . A right pleural pigtail catheter appears stable . There is no definitive evidence of pneumothorax . There is persistent hazy opacification at the right mid - to - lower lung zone and silhouetting of the right costophrenic angle compatible with small layering pleural effusion , unchanged . Blunting of the left costophrenic angle , most likely represents left basilar atelectasis with possible trace pleural fluid . The pulmonary vasculature is not engorged . The cardiomediastinal and hilar contours are within normal limits .
    OUTPUT:
    
No pneumothorax . Unchanged layering right pleural effusion and increased left basilar atelectasis .
