Patchy ill-defined mostly subpleural opacities are seen at both lungs suggestive for COVID19 pneumonia. There are also several atelectatic bands scattered bilaterally.

Case Discussion

Right-sided aortic arch is a type of aortic arch variations characterized by the aortic arch coursing to the right of the trachea. Different configurations can be found based on the supra-aortic branching patterns, with the two most common patterns being the right-sided aortic arch with mirror image branching and the right-sided aortic arch with aberrant left subclavian artery (ALSA).
