Anterior atlanto-occipital dislocation (type I dislocation): sagittal (right) reformatted CT image of craniocervical junction of a post-mortem CT study of a victim of young male patient who sustained high--force impact to the cranium as a result of an industrial accident with resultant bilateral atlanto-occipital dislocation (right joint dislocation indicated by arrow). The victim died at the scene: such craniocervical trauma carries a very high mortality and, as a result, ante-mortem imaging of such injuries is uncommon
