We report on the unusual presentation of a schwannoma. Aside from the aberrant dorsolateral anatomical presentation, ultrasonography revealed not only peripheral vascularity but also internal vascularity. Internal vascularity often suggests a malignant process as opposed to a benign one; however, in the presented case, the diagnosis of a benign lesion was confirmed with S100 immunohistochemical staining. In this study, we review the literature on this pathology and present an uncommon presentation of a benign nerve tumor.
