Ultrasound‐guided injection of botulinum toxin in a patient with omohyoid muscle syndrome: A case report

We present a case of omohyoid muscle syndrome diagnosed based on the clinical presentation and a dynamic imaging study. Botulinum toxin was injected into the inferior belly of one omohyoid muscle, and the neck mass resolved. © 2012 Wiley Periodicals, Inc. J Clin Ultrasound 41 :373–376, 2013
