Bilateral pallidotomy for severe dystonia in an 18-month-old child with glutaric aciduria.

Glutaric aciduria type 1 is an inborn error of metabolism due to deficiency of glutaryl-CoA dehydrogenase. This disorder mainly affects children. The majority of patients develop a dystonic-dyskinetic syndrome. The dystonia is painful and can cause significant disability. This report documents an 18-month-old child, the youngest reported, who underwent pallidotomy for disabling dystonia. The surgery improved dystonic symptoms, especially pain in this child with minor complications related to the procedure. Pallidotomy is a reasonable option for children with dystonic symptoms secondary to glutaric aciduria.
