Calcifications are prominent in the right and left neck likely reflecting prominent carotid bulb calcification . Bony defect at the right distal clavicle may reflect acute or chronic injury for which clinical correlation advised .
    OUTPUT:
    
1 . Emphysema with mild bibasilar atelectasis . 2 . Prominent carotid bulb calcifications and a carotid ultrasound may be considered to further assess . 3 . Bony defect at the right distal clavicle , correlate for focal pain as an acute fracture difficult to exclude .
