Brain MRI performed with 1 Brain MRI performed with 1.5-T equipment (sagittal T2 weighted; axial FLAIR, T1- and T2-weighted images). Brain MRI performed with 1.5-T equipment (sagittal T2 weighted; axial FLAIR, T1- and T2-weighted images). (Top) T1-weighted images following venous paramagnetic contrast at three planes. (Bottom) T2-weighted MRI of the brain reveals punctate nodular discrete hyperintense foci without a mass effect in the periventricular and subcortical white matter. These lesions do not increase.
