Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The study is slightly limited due to patient 's kyphotic positioning . The cardiac and mediastinal contours appear unchanged , with the heart size likely mildly enlarged . The aorta remains tortuous . There is crowding of the bronchovascular structures with possible mild pulmonary vascular congestion , but no overt pulmonary edema . No focal consolidation or pneumothorax is present . Blunting of the costophrenic angles posteriorly on the lateral view suggests the presence of trace bilateral pleural effusions . There are multilevel degenerative changes of the thoracic spine with a compression deformity of a lower thoracic vertebral body , unchanged . No pneumothorax is present .
    OUTPUT:
    
Probable mild pulmonary vascular congestion and blunting of the costophrenic angles posteriorly suggestive of small bilateral pleural effusions .
