Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low . This accentuates the size of the cardiac silhouette which is likely mildly enlarged . Aortic knob is calcified . Leftward tracheal deviation with fullness of the right superior mediastinal border may be due to the presence of the thyroid nodule or goiter . There is crowding of the bronchovascular structures without overt pulmonary edema . Patchy retrocardiac opacity likely reflects atelectasis . No pleural effusion or pneumothorax is demonstrated . Multilevel degenerative changes are noted in the thoracic spine .
    OUTPUT:
    
Low lung volumes . Left basilar atelectasis . Possible right - sided thyroid nodule or goiter resulting in leftward tracheal deviation . Clinical correlation is recommended and consider nonemergent thyroid ultrasound for further assessment if not done previously .
