Large irregular peripherally enhancing mass right parieto-temporal lobe. mass shows irregular thick wall enhancement with central necrotic component.  marked peritumoral edema and mass effect. Adjacent mass effect, compression on right lateral ventricle and third ventricle, compression on brain stem with contralateral midline shift (subfalcine herniation). Mild effacement of left lateral ventricle. 
Findings consistent with aggressive mass right parieto-temporal lobe likely Glioblastoma multiforme (GBM).
