    INPUT: Cardiac silhouette size is normal . Atherosclerotic calcifications are noted at the aortic arch . There is mild perihilar haziness and vascular indistinctness compatible with mild pulmonary vascular congestion . Additionally moderate size layering bilateral pleural effusions are relatively similar compared to the prior examination . Bibasilar opacities likely reflect compressive atelectasis . Marked degenerative changes of the left glenohumeral and acromioclavicular joint are noted along with multilevel degenerative changes in the imaged thoracic spine .
