Os odontoideum is an anomaly of the second cervical vertebrae in which the odontoid process is separated from the body of the axis. Traumatic injury or congenital fusion failure is thought to be the etiology. The clinical symptoms are variable from cervical pain, torticollis, and myelopathy and vertebrobasilar ischemia. Os odontoideum can cause instability of the neck, and neck injuries can cause life-threatening complications. In this report, we present the case of a 15-year-old girl with refractory epilepsy who developed quadriparesis after a fall and hit to the forehead while traveling. Although the symptoms improved, weakness in her right upper limb persisted at 2 months after the fall. Imaging studies revealed Os odontoideum. Based on her medical history, the recent head trauma due to epileptic seizures accompanied by atlantoaxial instability was considered to result in cervical compression and spinal damage. She was at a high risk of sudden death due to recurrent seizures and cervical injury; therefore, she underwent vertebral fusion surgery.
