Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lungs are hypoinflated with crowding of vasculature and increased interstitial markings suggesting component of mild pulmonary edema . Interval increase in right lower lobe opacity . Assessing for interval change of prior left effusions is difficult based on this single portable supine film . No visualized pneumothorax . Leftward deviation of the trachea is stable consistent with known multinodular goiter . Previously identified fiducial seed in the right hilus is not seen on today 's examination . Limited assessment of the osseous structures are unremarkable . No displaced rib fracture .
    OUTPUT:
    
No definite pleural effusion based on a single supine portable film . Consider lateral view for more detailed evaluation if desired . Mild pulmonary edema . Decreased retrocardiac opacity with new right lower lobe opacity which could be atelectasis . Differential includes pneumonia in the appropriate clinical setting .
