Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single frontal image of the chest demonstrates right - sided moderate - to - large pleural effusion and left - sided moderate pleural effusion , which are essentially unchanged from prior imaging . Again seen are left perihilar , right lower lobe , and left lower lobe opacities which are unchanged from prior imaging . The appearance of these opacities on this exam and on prior CTs likely represents aspiration . The opacity at the left lung base likely represents atelectasis adjacent to the left pleural effusion . There is no pneumothorax seen . Cardiomediastinal silhouette appears unchanged from prior imaging , but is incompletely assessed due to bilateral pleural effusions . An esophageal stent is seen consistent with patient 's history of esophageal cancer . A left - sided chest tube has been repositioned in the interval . A subclavian line is in place with the tip in the upper SVC .
    OUTPUT:
    
Essentially unchanged chest radiograph with bilateral pleural effusions , right greater than left , and opacities in the left perihilar , right lower lobe , and left lower lobe regions .
