Gliosarcoma: A rare variant of glioblastoma multiforme in paediatric patient: Case report and review of literature

Figure 1 Post contrast magnetic resonance imaging axial (A) and coronal (B) images shows large heterogeneous lesion in right parieto-occipital region with effacement of ipsilateral lateral ventricle.

Figure 2 Post-operative contrast magnetic resonance imaging axial (A) and (B) images shows complete excision of tumor.

Figure 3 Foci of reticulin-rich tumor cells also suggest sarcomatous component. A: Spindle shape tumor cell shows high MIB labelling index (MIB, × 400); B: Spindle shape tumor cell positive for vimentin (vimentin, × 400); C: Glial cell positive for glial fibrillary acidic protein (GFAP, × 400); D: Glial cell positive for glial fibrillary acidic protein (GFAP, × 100).
