In this report, we describe two rare cases with aortic branching anomalies. One was a 7-year-old girl who had an incomplete vascular ring caused by the presence of left aortic arch and aberrant, retroesophageal right subclavian artery associated with the common carotid trunk. The other was a 6-year-old boy who had a right aortic arch and mirror image branches of the former case. Both were asymptomatic and discovered incidentally. Three-dimensional surface rendering magnetic resonance angiography was used to confirm the diagnosis. Surgical intervention was not performed in either case because of lack of vascular ring-related symptoms. The incidence, clinical symptoms, pathogenesis and management of this rare vascular ring are discussed below.
