Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low . Heart size is at least moderately enlarged . Mediastinal contours are unchanged . Mild pulmonary edema is noted , worse in the interval . Small bilateral pleural effusions are likely present with bibasilar airspace opacities , most likely reflective of atelectasis . No pneumothorax is identified . Percutaneous catheter is noted with pigtail in the right upper quadrant of the abdomen . Left PICC tip now appears to be flipped , likely within the azygos .
    OUTPUT:
    
1 . Mild pulmonary edema and small bilateral pleural effusions . Bibasilar airspace opacities , likely compressive atelectasis . Infection is not excluded . 2 . PICC tip appears to be flipped in the interval , potentially within the azygos . This can be confirmed with a lateral view .
