Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The ET tube terminates approximately 2 .5 cm above the carina . Although there is a generalized increase in radiodensity in the right lung , which could be secondary to edema , increased opacification at the right lung apex at the site of prior radiation injury , may be secondary to pneumonia . Diffuse interstitial abnormality , particularly within the right upper lobe is compatible with patient 's known lymphangitic spread of cancer as seen on the prior chest CT examination , and overall appears slightly worse compared to the prior exam . Mild left basilar atelectasis is persistent . Small bilateral pleural effusions are stable . There is no evidence of a pneumothorax . The heart size is normal .
    OUTPUT:
    
1 . Generalized increase in radiodensity in the right lung may be secondary to edema , however , pronounced opacification , particularly at the right lung apex is concerning for pneumonia . 2 . Diffuse interstitial abnormality throughout the right lung is consistent with patient 's known lymphangitic spread of cancer . 3 . ET tube terminates approximately 2 .5 cm above the carina .
