Successful Conservative Treatment of a Kommerell Aneurysm Associated With Right-Sided Aortic Arch.

Right-side aortic arch is a rare congenital aortic anomaly occurring in 0.05% to 0.1% of the general population. Approximately, half of these cases may be associated with an aberrant left subclavian artery and occasionally with aneurysmatic change at its origin known as Kommerell diverticulum or aneurysm (KA). Herein we report a challenging case of a right-side aortic arch associated with KA incidentally observed in a 73-year-old male with metastatic lung cancer. After careful multidisciplinary discussion, a conservative strategy of care was successfully adopted.
