MRI - MRI Brain
An ill defined diffuse infiltrative process involving the deep white matter of left cerebral hemisphere mainly the temporal, frontal and parietal lobes, internal and external capsules, thalamus, left cerebral peduncle and left hemipons and contralaterally it extends through the corpus callosum to the right forceps minor fibers. The lesion displays bright signal on T2 and FLAIR, iso intense signal on T1 with no significant contrast enhancement or diffusion restriction. Mass effect in form of subfalcine herniation causing right lateral ventricular dilatation and transependymal CSF leakage are noted as well.
