MRI confirms a large, heterogeneous, mass involving the left temporoparietooccipital lobes which extends across the splenium of the corpus callosum. There is a slight extension of the mass into the right occipital parenchyma. The lesion is partly solid, with necrotic & hemorrhagic (see the blooming on T2* GRE) components. Associated local mass effect & oedema. The findings are compatible with glioblastoma multiforme.
There is no abnormal leptomeningeal enhancement.
