Figure 1
Sagittal reformat (a) of noncontrast cervical CT shows a cleft in the basal odontoid (blue arrow) suggestive of a midline integration defect with persistent ossiculum terminale (white arrow). Note hypertrophied anterior arch of atlas (yellow arrow). Coronal reformat (b, c) of the same shows persistent ossiculum terminale (white arrow in b and c) with midline integration defect of the basal odontoid (black arrow in b). Lateral cervical radiograph in flexion (d) shows anterior displacement of the anterior arch of atlas and ossiculum terminale (arrow) relative to the position in extension (arrow in e) and neutral position (arrow in f)

Figure 2
Sagittal T2 weighted image (a) shows persistent ossiculum terminale (white arrowhead) with midline integration defect of the basal odontoid (yellow arrow). Loss of flow void is seen in the basilar artery (red arrow) with a chronic infarct in the pons (black arrow). Axial T2 weighted images (b, c) show a chronic pontine infarct (black arrow in b) with loss of flow void in V4 segment of both vertebral arteries (arrowheads in c). TOF-MRA (d, e) show nonvisualization of both vertebral arteries and the basilar artery with bilateral fetal posterior cerebral arteries (arrows in d). Post-contrast axial T1-SPACE (f) shows subtle eccentric hyperintensity along the V4 segment of both vertebral arteries (white arrowheads)
