Congenital atlantoaxial rotatory displacement. a Mid-sagittal T2W sequence of the cervical spinal cord revealing an intramedullary spinal lesion suggestive of gliosis or vasogenic oedema. b Transverse computed tomography of the atlantoaxial junction revealing asymmetry of the articular facets of the axis. There is hypertrophy of the articular facet on the left side and obvious rotation of the atlantoaxial joint. c Dorsal view of a 3D CT-reconstruction of the cervical spine showing atlantoaxial rotation. d Flexed right lateral radiograph of the cervical spine demonstrating lack of obvious atlantoaxial instability. e Right lateral post-operative radiograph of the cervical spine revealing an adequate implant positioning
