Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiomediastinal contour remains enlarged , partially attributable to the presence of bilateral paramediastinal radiation fibrosis , and appears slightly enlarged compared to the prior chest radiograph . Small left pleural effusion which is partially loculated laterally is unchanged . Increased interstitial markings are again seen in both lung bases , present on the prior chest CT , and again may reflect mild pulmonary edema or lymphangitic spread . No new focal consolidation , right - sided pleural effusion or pneumothorax is demonstrated . Distal posterior mediastinal clips are re - demonstrated .
    OUTPUT:
    
Slightly increased size of the cardiomediastinal contour compared to the prior chest radiograph , and could be due to the presence of an increased pericardial effusion . Unchanged appearance of small partially loculated left pleural effusion . Increased interstitial opacities in the lung bases are similar compared to the prior chest CT , and again may reflect mild fluid overload or lymphangitic spread of tumor .
