Introduction: The Craniovertebral Junction (CVJ) comprises of the skull base (occipital bone), upper cervical spine (atlas and axis) and surrounding neurovascular structures, including the brainstem, spinal cord and vertebral arteries. Its stability depends on strong ligaments, membranes and bony anatomy, allowing key movements like rotation and flexion-extension. Cervical myelopathy significantly affects quality of life and can be caused by both common and rare causes. Common causes include degenerative disc disease, cervical spondylosis, spinal stenosis, herniated discs and trauma, all of which lead to compression of the spinal cord due to wear, injury, or misalignment in the cervical spine. Less common causes involve congenital abnormalities in the spinal structure, tumours, infections, rheumatoid arthritis, atlanto-occipital membrane issues and Chiari malformation, all of which lead to spinal cord compression. Despite a thorough diagnostic evaluation, around 20% of cases remain idiopathic. The authors hereby, present a case of a 59-year-old male with suboccipital and neck pain radiating predominantly to the left upper and lower limbs, accompanied by paraesthesias. Imaging revealed a congenital anomaly of the atlas, characterised by the absence of the left half of the posterior arch (Currarino type B). This structural defect led to stretching and ventral displacement of the Posterior Atlanto-occipital Membrane (PAOM), resulting in compression and myelomalacia of left hemispinal cord.
