Presentation
Chest pain with intermittent dysphagia
Patient Data
The frontal view shows a prominent right aortic arch with a slight tracheal shift to the left.
The lungs are clear.
The heart size is normal.
The MRI sequences demonstrate a right-sided aortic arch with aberrant left subclavian artery associated with Kommerell's diverticulum. The aortic arch crosses the midline posterior to the trachea and esophagus which are displaced anteriorly with significant compression of the esophagus.
The barium swallow reveals a smooth regular extrinsic compression of the esophagus.
Case Discussion
Radiologic and MRI features of a right-sided aortic arch with aberrant left subclavian artery associated with Kommerell's diverticulum. Together these findings constitute a type II right-sided aortic arch. It can rarely cause esophageal and/or tracheal compression (as in this case).
