MRI
Right parietal parafalcine cortical/gyral space occupying lesions of abnormal signal. They elicit isointense signal at T1 WI, low signal at T2 WI with diffusion restriction and marginal nodular post contrast enhancement. The lesions are surrounded by subcortical vasogenic edema signal which exert positive mass effect in the form of ipsilateral right lateral ventricle and effacement of the overlying cortical sulci.
