Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Mild enlargement of cardiac silhouette persists . The aorta is diffusely calcified and tortuous . Mediastinal contours are unchanged . There is mild pulmonary edema with perihilar haziness and vascular indistinctness , perhaps minimally worse since the previous study . Blunting of the costophrenic angles bilaterally is compatible with small bilateral pleural effusions . More focal opacity within the lung bases could reflect areas of atelectasis . No pneumothorax is present . Degenerative changes are seen within the glenohumeral joints bilaterally as well as diffusely throughout the thoracic spine . Healed fracture deformity of the left mid clavicle is again noted .
    OUTPUT:
    
Mild pulmonary edema and small bilateral pleural effusions with probable bibasilar atelectasis .
