Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Severe rotary dextroscoliosis of the thoracolumbar spine is demonstrated . Large left and moderate - to - large right pleural effusions appear slightly increased in size compared to the prior study . Evaluation of the cardiac silhouette size is limited due to the presence of the bilateral pleural effusions . There is marked calcification of the thoracic aorta . Hazy perihilar opacities with engorgement of the pulmonary vascularity suggests mild pulmonary edema . There is bibasilar airspace opacities likely reflective compressive atelectasis . No pneumothorax is present . Known free air within the abdomen seen on the recent CT at 15 :41 performed the same day is not clearly noted on the current exam . Excreted contrast material is noted within the left collecting system . Evaluation for rib fractures is limited , though no markedly displaced rib fractures are present .
    OUTPUT:
    
1 . Large left and moderate - to - large right , bilateral pleural effusions with bibasilar airspace opacities likely reflecting compressive atelectasis . 2 . Mild pulmonary edema . 3 . Known free air within the abdomen is not clearly visualized on the current study . 4 . No displaced rib fractures are noted . The study , however , is limited for the detection of rib fractures , though no acute rib fractures in the lower thorax were demonstrated on the recent CT of the abdomen .
