I would like to thank Dr. Stasolla for his kind words in reference to my article, “The Many Faces of Facial Nerve Schwannoma.”1 Although the “dural tail” sign has been reported with many pathologies, including acoustic schwannomas, none of the cases in my series demonstrated a dural tail on imaging. It is always difficult to interpret cases solely on the basis of a text description, but the case Dr. Stasolla describes in his letter is consistent with a facial nerve schwannoma. Both the clinical and imaging descriptions are consistent with the findings in my series, with a peripheral facial neuropathy in 10 cases (42%) and some type of hearing loss in 11 cases (46%), and for the radiologic description (benign osseous remodeling on CT and enhancing lesion along the course of the facial nerve on MR imaging).

I agree with Dr. Stasolla that there are a variety of etiologies that can lead to a dural tail sign in MR imaging, and I would be happy to review his case because I am always interested in seeing good head and neck cases.
