Fig 1 Computed tomography (CT) carotid angiogram showing a hypoplastic artery entering the carotid canal confirming that it is a hypoplastic right internal carotid artery (ICA). The stenosed origin is also demonstrated. A, Hypoplastic ICA; B, carotid canal; C, external carotid artery; D, diseased origin of the hypoplastic ICA.
