Abstract: We report the case of a 23-year-old healthy man who had sudden onset of cervical dystonia spasmodic torticollis in October 2012. He was treated with intravenous cidofovir, which was started on February 20, 2013, followed by oral valganciclovir and famciclovir. Pulling of the neck and tilt of the head far to the left is no longer present (as at April 22, 2014). Human herpesvirus 6 total antibody titers fell from 11.27 (negative <1) on January 15, 2013 to 1.89 on August 5, 2013. To our knowledge, this is the first case of improvement in cervical dystonia spasmodic torticollis with treatment.
