Adolescent Idiopathic Scoliosis (AIS) is a 3-dimensional spinal deformity which occurs predominantly in adolescent girls. Impaired postural balance and tonsillar ectopia are reported findings in AIS. This study sought to investigate and compare white matter integrity of the cerebellar pathways in AIS with matched controls. Anatomically-guided deterministic tractography was used to reconstruct the cerebellar pathways. Lower FA value was found in spinocerebellar tract and in intracerebellar tract in AIS, suggestive of, reduced white matter integrity of the cerebellar pathway, which is in agreement with similar changes in other white matter pathways within the brain of AIS patients.
