T1WI [Figure 1] and a high signal on T2WI [Figure 2] and a hyperintense region around the tumor on FLAIR sequence. Additionally, peritumoral edema and mass effects were seen in the form of a midline shift. The posterior horn of the lateral ventricle and the third ventricle were compressed and deviated anteriorly. The Gd contrast enhanced scan [Figure 3a and b] showed enhancement of the lesion wall.
T2 weighted axial image at the level of head of caudate nucleus shows the peritumoral edema (small arrow) multinodular lesion in the temporooccipital lobe (large arrow).

T1WI [Figure 1] and a high signal on T2WI [Figure 2] and a hyperintense region around the tumor on FLAIR sequence. Additionally, peritumoral edema and mass effects were seen in the form of a midline shift. The posterior horn of the lateral ventricle and the third ventricle were compressed and deviated anteriorly. The Gd contrast enhanced scan [Figure 3a and b] showed enhancement of the lesion wall.
Glial Fibrillary Acidic Protein (GFAP) stained histopatholgy slide shows the specific glioneuronal elements (arrow). Immunohistochemistry for glial fibrillary acidic protein (GFAP), S-100 protein, establish the presence of astrocytic and neuronal components, while GFAP reactivity is negative for an oligodendrocytic component
