CV Junction Potts Spine-MRI

Cervical Pott’s disease is unusual. Furthermore, CVJ tuberculosis has been reported to affect 0.3% to 1% of all Pott’s disease patients. This is a 9year old boy with potts spine with cranial migration of the odontoid process and retropharyngeal abscess. Note the impingement of brainstem with odontoid process.  The occipito-cervical junction, a transitional zone between the skull and the spinal column, serves as the most mobile part of the axial skeleton. Bony abnormalities affecting this complex results in dysfunction of the neural structures by compression along the entire circumference, altering the arterial supply, venous drainage and changing the CSF fluid dynamics.
