case_images: On plain CT scan of the head (Figure 1), there was a complex lesion with cystic and solid components and calcification along left parieto-occipital lobe associated with florid vasogenic edema.

case_images: This was alternated by a sarcomatous part revealing fascicles of spindle cells with atypical, highly pleomorphic nuclei (some bizarre nuclei) (Figure 2).
case_images: Immunohistochemical and special stains; A) reticulin in sarcomatous component; B) vimentin in sarcomatous component; C) GFAP in glial and sarcomatous component; D) GFAP in glial component

case_images: Immunohistochemical analysis revealed the glial component to be Glial Fibrillary Acidic Protein (GFAP) positive and the sarcomatous component as diffusely positive for reticulin and vimentin but negative for GFAP Figure 3.
