case_images: F1
case_images: The tumor was isointense on T1WI and T1-gadolinium showed annular enhancement of the lesion (Fig. 1).
case_images: Histopathological study showed a schwannoma with biphasic components (hypercellular and hypocellular areas) (a). Immunohistochemical studies showed strong reactivity for S-100 Protein (b). Glial Fibrillary Acidic Protein (GFAP), Epithelial Membrane Antigen (EMA) and Progesterone Receptors (PR) were negative (c). A low rate proliferative index was demonstrated by Ki-67 expression (d).

case_images: Acidic Protein (GFAP), Epithelial Membrane Antigen (EMA), Progesterone Receptors (PR), and Ki-67 were tested. Altogether, these findings confirmed schwannoma and excluded glioma and meningioma (Fig. 2).
