Given differences in positioning , noting lordosis on the current exam , there has been no significant interval change . There is no definite confluent consolidation . Mild cardiomegaly is also likely accentuated for the reasons stated above . Dense mitral annular calcifications are noted . Osseous structures are grossly unremarkable . There is mild left lateral deviation of the trachea just proximal to the thoracic inlet , raising the possibility of underlying thyroid enlargement .
    OUTPUT:
    
1 . Probable mild cardiomegaly without definite acute cardiopulmonary process given positioning and technique . 2 . Possible mild left tracheal deviation , just above the thoracic inlet , raising possibility of right - sided thyroid enlargement . Ultrasound could further characterize if desired .
