Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is a diffuse opacity occupying nearly the totality of the right lung with some sparing of the right apex which appears mildly increased compared with prior CT . In the left lung , there is a new ill - defined opacity in the left upper lung field . Prominence of the left hilum represents known hilar lymphadenopathy . There are small bilateral pleural effusions . The heart size is normal , and a superior vena cava stent is noted . There is no evidence of pneumothorax .
    OUTPUT:
    
1 . Increased opacity in the right lung is consistent with worsening lymphangitic carcinomatosis , although superimposed pneumonia can not be excluded . 2 . New ill - defined opacity in the left upper lung might represent a new neoplastic focus versus infection .
