DYT6 Dystonia Mimicking Adolescent Idiopathic Scoliosis Successfully Treated by Pallidal Stimulation.

An adolescent DYT6 patient with dystonia-related severe scoliosis was treated by bilateral GPi-DBS. The patient had an excellent outcome at 12 months after surgery, which prevented him from developing severe spinal deformity and disability. Early diagnosis of dystonia in adolescent patients can lead to timely and effective treatment. The etiology of severe scoliosis in adolescents should be carefully evaluated and differential diagnosis including dystonia should be considered. GPi-DBS in patients with DYT6 dystonia can prevent deformity.
