case_images: preoperative magnetic resonance imaging of the brain showing an extra-axial lesion in the right temporal fossa with two components solid and cystic (A) isointense on T1 weighted-images, (B) heterogeneously enhanced in T1 weighted-images, and (C) isointense on T2 weighted-images

case_images: The solid mass measuring 22*28*20 mm was isointense on T1-weighted images (T1w), isointense on T2-weighted images (T2w), and heterogeneously enhanced (Figure 1).
case_images: histopathological examination: (A) mixed population of spindled and epithelioid cells (Hematoxylin Eosin X100); (B) pleomorphic and xanthomatous cells with intracytoplasmic eosinophilic granular bodies (Hematoxylin Eosin X400)

case_images: Diagnosis: on histopathological examination (Figure 2), hematoxylin and eosin-stained sections showed a tumor composed of spindle and epithelioid cells arranged in sheets and fascicles admixed multinucleated giant cells.
case_images: immunohistochemical examination: (A) positive immunostaining for S100 protein (X100); (B) diffuse positive immunostaining for glial fibrillary acid protein (X100)

case_images: On the immunohistochemical examination (Figure 3), the neoplastic cells were positive for glial fibrillary acidic protein (GFAP), PS100, vimentin, and reticulin.

case_images: A postoperative MRI of the brain performed 18 months after surgery, confirmed the absence of tumor recurrence (Figure 4).
