Figure 1: Noncontrast computed tomography (a) axial image showed symmetrical periventricular and deep white matter hypodensities with cerebral atrophy. Coronal plain T1 (b) image showed hypointense signal involving periventricular and deep white matter. Axial T2w (c) section showing symmetric periventricular and deep white matter hyperintensity. Axial ADC (d) and DWI (e) sections showed corresponding patchy areas of diffusion restrictions involving periventricular and deep white matter. Axial Fluid Attenuated Inversion Recovery (FLAIR) (f) image showed hyperintense signal involving similar areas and ex-vacuo prominence of bilateral lateral ventricles. No areas of any blooming were noted on SWI sequence (not shown). Midsagittal FLAIR (g) & Axial (high frontoparietal) (h) image showed patchy involvement of corpus callosum with sparing of subcortical white matter. TOF Angiography study (i) showed normal circle of Willis. PET-CT Brain Fused images axial sections [j (1-4)] showed diffuse decrease in tracer uptake in left parietal, temporal region (Blue arrow) as compared to the right side without any increased uptake in periventricular and deep white matter
