    INPUT: The heart size is mildly enlarged . The aorta appears dilated and tortuous . Fullness of the superior mediastinal contour is also demonstrated without tracheal deviation . There is no pulmonary vascular congestion . Linear opacities in the left lung base likely reflect atelectasis . Eventration the right hemidiaphragm is noted . There is no focal consolidation , pleural effusion or pneumothorax . No acute osseous abnormalities are detected . An electronic device is seen projecting over the midline left chest .
    OUTPUT:
    
1 . Tortuous and dilated aorta . 2 . Widening of the superior mediastinal contour could reflect a thyroid goiter . Comparison with prior imaging is recommended , and if none has been obtained , a CT of the chest is suggested for improved assessment of the mediastinum and the aorta . 3 . Left basilar atelectasis .
