Sub-occipital Pott's disease: imagery contribution about two cases

Pott's disease is the most common form of bone ann joint tuberculosis, nota bly in the thoracolumbar spine. The sub-occipital localization remains exce ptional, raising a major risk of spinal instability and severe bulbo-medull ary complications. We report 2 new cases of tuberculous spondylodiscitis at the cervico-occipital junction revealed by signs of spinal compression ass ociated with torticolis and dysphagia. The diagnosis was provided by CT sca n and MR imaging and was confirmed histologically on a transoral biopsy of the retorpharyngeal abscess. The patients were successfully treated with an tituberculosis drugs combined with external stabilization of the spine. The diagnostic aspects, notably the neuroradiological findings in this particu lar localization of Pott's disease are recalled.
