Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Right PICC tip terminates in the mid SVC . Esophageal stent is re - demonstrated in unchanged position . The heart size is top normal . The aorta is tortuous and diffusely calcified . Prominence of the mediastinal contour is unchanged , compatible with known small cell lung cancer . There is mild pulmonary edema with moderate bilateral pleural effusions , right greater than left , slightly improved when compared to the prior exam . Bibasilar opacities likely reflect compressive atelectasis but infection or aspiration is difficult to exclude . No pneumothorax is detected . Multiple clips are again demonstrated within the upper abdomen . No acute osseous abnormalities are seen .
    OUTPUT:
    
Mild pulmonary edema , and moderate size bilateral pleural effusions , minimally improved , with bibasilar compressive atelectasis . Infection or aspiration of the lung bases is difficult to exclude .
