Erratum

The article entitled “The Rare Third Branchial Cleft Cyst” (AJNR Am J Neuroradiol 2009;30:1804–06) mistakenly stated that the third arch gives rise to the superior laryngeal constrictor muscles and the inferior aspect of the thyroid gland. The article should have correctly stated that the third arch gives rise to the inferior parathyroid glands and the stylopharyngeus muscle, not the aforementioned structures.
