Learning objectives 1) To understand the relevance of knowledge of craniovertebral junction relationships, typical anatomical landmarks, and craniometry. 2) To localize, describe, and characterize craniovertebral junction abnormalities and CVJ pathologic imaging findings.3) To emphasize clinical implications to improve our radiological report.
Read more Background CVJ is a collective term that refers to the occiput, atlas, axis, and supporting ligaments. It encloses the soft tissue structures of the cervicomedullary junction. Includes:The caudal portion of the brainstem (Medulla)CerebellumFourth ventricleThe rostral part of the spinal cordLower cranial & upper cervical nerves CVJ is divided into two components concerning the governance of inter-segmental movements: [fig 1] The central pivot: Dens and the C2 vertebral body & Basiocciput.Two ringed structures: Foramen Magnum  & Atlantal ringVIEWS & IMAGING ESSENTIALS:Plain Radiographs               lateral view               AP  view ...
Read more Findings and procedure details LIGAMENTOUS  ANATOMY: PRIMARY STABILISERS  [fig 2] Transverse Atlantal Ligament  (TAL) TAL is a thick band posterior to dens attached to tubercles of atlas.Allows free gliding motion to occur over the posterior facet of the dens.TAL effectively limits anterior translation and flexion of the atlantoaxial joint.Alar Ligaments: Two strong cords attached to the dorso- lateral body of the dens &  extend laterally  & rostrally.They are ventral & cranial to the transverse ligament.The alar ligament allows an anterior shift of C1 from 3 to 5 mm.SECONDARY STABILISING...
Read more Conclusion The craniovertebral junction is functionally and anatomically a complex region. It is often a site for congenital and acquired anomalies, some of which are treatable neurological disorders. Adequate knowledge of regional embryology and an understanding of the anatomical complexity and range of regional disease processes are essential for arriving at an accurate diagnosis. While plain radiographs have an important role initially, multiplanar imaging with CT and MRI provides more specific and detailed information on bony and soft tissue structures. This...
