Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low . Cardiac silhouette size remains mildly enlarged . The mediastinal contours are unchanged . Diffuse hazy ill - defined opacities are noted in the lungs , more extensive than compared to the previous exam . Small bilateral pleural effusions persist , not substantially changed in the interval . Bibasilar atelectasis remains similar compared to the prior exam . Assessment for pneumothorax is limited on this exam due to the patient 's chin and neck soft tissues obscuring the lung apices , though no large pneumothorax is detected .
    OUTPUT:
    
Diffuse hazy opacities in the lungs , progressed since the previous study . This could reflect worsening multifocal pneumonia though an element of superimposed pulmonary edema may be present . Small bilateral pleural effusions persist , and there is continued bibasilar atelectasis .
