Background
· Craniocervical junction is the anatomical region formed by the occipital bone, foramen magnus, clivus, atlas, axis, supporting ligaments and soft tissue structures of the cervico medullary junction (1,2)
· The ligaments connecting the bones are articular capsules, anterior atlantooccipital membrane, posterior atlantooccipital membrane, lateral
ligaments and synovial membranes (1,2)
· Due to anatomic complexities of the CVJ and high frequency of craniocervical trauma with muscle spasm, plain radiographs pose limitations in accurate diagnosis(9).
· The cross-sectional imaging such as MDCT and MRI are used for for further diadnosis, as MDCT is ideal modality for evaluation of complex osseous anatomy associated with CVJ abnormalities while MRI, with its multi-planar capabilities and high soft tissue contrast resolution, has become the mainstay in radiological evaluation of the CVJ(9).
