Figure 3: On computed tomographic angio, the left vertebral artery was hypoplastic and C2 segmental type while the dominant right sided vertebral artery was C3 type (a). On magnetic resonance imaging, there is cord intensity change at the level of C2 with intradural vertebral artery at the same level (b). There was associated hypoplasia of the right C2 hemilamina and poor visualization of the distal BA. Sagittal computed tomography of second patient show anterior atlanto-axial dislocation with mild basilar invagination (c). Postoperatively, there was total correction of the dislocation on postoperative computed tomographic with well-placed screws (d)
