Occipital neuralgia is usually unilateral and has a characteristic shock like pain lasting for a short duration indicative of neural origin. The pain is confined to the dermatome of the nerve root at the lower occipital region of scalp and upper neck. The C3 nerve root compression can occur at the spinal canal lateral recess, neural foramina and lateral to the foramina. Compression of the nerve root by an abnormal course of vertebral artery has been reported in the literature. Bony abnormalities at the craniovertebral junction can cause occipital headache due to abnormal course of vertebral artery and joint instability. Foramen transversarium defect of upper cervical vertebrae though not included in the cervicovertebral junction anomaly, when anomalous can cause occipital headache as in this case.
