Congenital anomalies of the aortic arch are rare, with very few cases reported in the literature. Congenital absence of the common carotid artery (CCA), with separate origins of the internal carotid artery (ICA) and external carotid artery (ECA) is a rare anomaly. This case illustrates a congenital anomaly in the development of the right carotid system. By use of duplex sonography, we report of the absence of the right CCA with separate ICA and ECA originating from the innominate artery.
