Abstract
Isolated aortic arch vessels arising anomalously from the pulmonary arterial system are rare congenital anomalies. Case reports of isolated arch vessels are often associated with 22q11 deletion, CHARGE syndrome, or right aortic arch. Isolation of the carotid artery may lead to cerebral steal phenomenon and ischemia or to pulmonary overcirculation. The authors report what is, to their knowledge, the first case of isolated right common carotid artery arising from the right pulmonary artery, associated with 22q11 deletion, and describe the challenging multimodality image evaluation.
