T2-weighted magnetic resonance imaging confirmed a heterogeneous hyperintense tumor occupying the anterior cranial fossa without dural penetration (Fig. 1).
Neopasm consisting of elongated spindle cells with poorly defined, palely eosinophil cytoplasm, sometime with nuclear palisading. Immunohistochemically, glial fibrillary acidic protein (GFAP) was negative and vimentin and S-100 protein stained intensively.
