Barium Swallow Aspiration
Barium swallow in the LPO projection shows abnormal accumulation of contrast along the walls of the trachea (b, white arrowheads) secondary to aspiration. Contrast also lines the wall of the posteriorly positioned esophagus (b, light green arrowheads) with a small air fluid level in the primary stripping wave of the esophagus (b, lower light green arrowhead). The contrast lined superior aspect of the epiglottis (pink arrowhead) is seen among the vallecula and pyriform sinuses.
