Main Article Content


Os odontoideum is an anomaly of the second cervical vertebra (axis). This has as a correlate the spinal cord compression into the occipito-cervical spinal canal. It is a rare condition with an unknown exact prevalence. We reported the case of an 8-year-old patient presenting with quadriparesis for 9 months evolution. The diagnosis was made on a head CT scan and a MRI of the cervical spine.


Os odontoïdeum (OO) est une anomalie de la deuxième vertèbre cervicale ou axis. Il a pour corollaire la compression médullaire dans le canal rachidien cervico occipital. C’est une affection rare, sa fréquence exacte est inconnue. Nous vous rapportons le cas d’une patiente de 8 ans avec une tétraparésie évoluant depuis 9 mois. Le diagnostic a été révélé lors de la réalisation d’un scanner cérébral compléter par une IRM du rachis cervical.
