Normal esophageal contours on barium swallow

There are a number of normal esophageal contours or impressions that are encountered when performing a barium swallow. It is important to be able to differentiate normal contours and their variants, as well as contours that may indicate disease. Below is a list of anatomical structures that may be seen in a normal barium swallow:

• cricopharyngeus muscle (cricopharyngeal bar)
• aorta
• left main bronchus
• left atrium

Anatomical variants

• aberrant right subclavian artery (arteria lusoria)
• aberrant left pulmonary artery
