Multi-modal brain MRI. Axial T2-weighted (a) and FLAIR images (b) depicted T2 hyper-intensity and sagittal T1-weighted MRI (e) showed hypo-intensity in the genu, body and splenium of the corpus callosum. Axial DWI demonstrated high signal intensity in the observed T2 abnormality of the lesions of the corpus callosum (c). Corresponding ADC map illustrated matched abnormality, confirming restricted diffusion in the corpus callosum (d). MRA showed the absence of the A1 segment of the bilateral anterior cerebral artery. Atherosclerotic segment of stenosis in the area of the bilateral middle cerebral artery and left posterior cerebral artery were noted (arrows) (f).
