Figure 3: Preoperative images (Case 2). (a) T2-weighted magnetic resonance imaging showing Chiari formation and syringomyelia. (b) Computed tomography scan with the head in flexed position showing foramen magnum decompression. Atlantodental interval is normal. (c) Computed tomography scan with the sagittal cut passing through the facets showing the facets are in alignment. (d) 3-D computed tomography scan showing foramen magnum decompression and resection of arch of atlas
