The 64-slice chest computed tomography (CT) with contrast material showed bibasilar bronchiectasis (Fig. 1) and ARSA with Kommerell diverticulum.
The sagittal view of chest CT revealed ARSA behind the esophagus (red arrow) and the calcified trachea in front of it. Dilation of esophagus above and below the aberrant artery was sign of the esophageal obstruction.

On the sagittal view of chest CT (Fig. 2), the calcification of trachea in front of and the presence of ARSA behind the esophagus created the pressure clip inducing esophageal obstruction which was proved by dilation of the esophagus above the clip.
