  Fig. 1 Axial fluid-attenuated inversion recovery MRI scan (A) showing no focal abnormalities in signal intensities within the brain. Note the mild asymmetry of the lateral ventricles (arrow). Perfusion dynamic susceptibility contrast MRI with MTT map (B and C) shows asymmetric perfusion of the cerebral hemispheres with a high MTT (green color) in the right frontoparietal area. CT angiography (E) with the VRT and maximum intensity projection (D) clearly shows the normal carotid artery bifurcation on the right side (asterisks) and the complete absence of the cervical and intracranial left internal carotid artery, with the left common carotid artery continuing as an external carotid artery (arrow). Axial CT scan with a bone algorithm at the skull base (F and G) shows that the bony carotid canal is absent on the left side (arrows) and has developed normally on the right side (asterisks). CT angiography with the VRT (H) shows normal flow in the left middle cerebral artery, supplied by a large posterior communicating artery (arrow). CT: computed tomography, MRI: magnetic resonance imaging, MTT: mean transit time, VRT: volume rendering technique.
