【 摘 要 】

Vertebral artery agenesis is a rare congenital malformation , with few reported cases in the literature and no epidemiological data in the world at this point in time. The importance of diagnosis lies in identifying a potential risk factor for future ischemic events of the posterior circulation, in particular in the young population. It is also important to determine the etiology of chronic headache of unexplained cause that could be attributed to this entity. The present case describes this finding in a 27-year-old female patient with no pathological history, with multiple stab wounds was brought to the emergency room of our hospital .During the study of whether the wounds caused had been penetrating to the neck, a CT angiography was performed. The CT documented an incidental finding of absent left transverse foramen of the cervical vertebrae , absence of the left vertebral artery from its origin in the ipsilateral subclavian artery and a single dolichoectatic right vertebral artery crossing the midline at the entrance to the foramen magnum .
