Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Port -A - Cath terminates in the uppermost atrium . Lung volumes are low , obscuring cardiac borders , but there is no clear change in cardiac , mediastinal or hilar borders . There is new opacification at the left lung base suggesting a pleural effusion . There is a small , persistent left - sided pneumothorax , but decreased . On the right , although pleural effusion has decreased , there is new focal opacity at the right lung base in addition to diffuse increased opacification of each lung .
    OUTPUT:
    
Increased diffuse opacification suggesting pulmonary edema or possibly widespread pneumonia . New right base opacity suggesting atelectasis , potentially pneumonia . Persistent but decreased left - sided pneumothorax .
