Geniculo-Temporo-Parotideal Neurofibroma of the Facial Nerve

Abstract

Preoperative diagnosis of facial nerve neurofibroma is difficult when it presents as an asymptomatic parotideal mass. Facial nerve tumor suspicion arises during parotid surgery, histopathologic evaluation confirms diagnosis and postoperative imaging demonstrates a nerve tumor and its extension. We present the multimodality imaging findings of a 43-year-old man with a solitary neurofibroma involving the whole facial nerve continuously from geniculate ganglion to parotideal segment as the first case in the literature.
