Erratum
=======


[The letter reply by Drs. Gasparetto, Nirenberg, and Marcondes de Souza in the June-July issue (AJNR Am J Neuroradiol 2009;30:E84)](http://www.ajnr.org/lookup/volpage/30/e84?iss=6) incorrectly identified a dermoid tumor as an epidermoid tumor in both the text and figure legend. The authors regret this error.
