Introduction: Seven cervical vertebrae constitute the skeletal framework of the neck. Along with the other identification points, the cardinal feature of a cervical vertebra whether typical or atypical is the presence of Foramen transversarium on the transverse process. This foramen transmits the Vertebral artery, Vertebral vein and Sympathetic nerves. These foramina are known to have variations in size, shape and numbers and may be absent, incomplete or duplicate, which may lead to various symptoms. Their etiology is related with the variations in the course of the Vertebral artery due to developmental reasons.
