      Abstract

      A patient whose chest computed tomography scan demonstrated a right-sided aortic arch with an aberrant retroesophageal left innominate artery is reported. There have been only isolated case reports of this developmental variation of the arch and great vessels. The demonstration of this anomaly by computed tomography scanning has never been previously reported.
