Axial diffusion weighted images (a, b) and corresponding apparent diffusion coefficient (ADC) maps (c, d) of magnetic resonance imaging of the brain done on day 4, show diffuse symmetric areas of restricted diffusion in bilateral cerebral hemispheres, involving mainly white matter. The perirolandic regions and basal ganglia are spared.

Adjacent cortices were also hyperintense [Figure 1a-d].
Axial T1 weighted (a) and T2 weighted (b) images, at the level of basal ganglia, show that corresponding areas of restricted diffusion do not reveal any signal abnormality.

T1 and T2 weighted images [Figure 2a and b]. The perirolandic regions and basal ganglia were spared, excluding the diagnosis of hypoxic-ischemic injury.
Axial fluid attenuated inversion recovery (FLAIR) (a), diffusion weighted image (b) and corresponding apparent diffusion coefficient (ADC) map (c) of magnetic resonance imaging of the brain done after 4 weeks shows resolution of diffusion abnormalities and mild generalized cerebral atrophy.

A follow-up MRI done after 4 weeks revealed resolution of diffusion weighted abnormalities and mild generalized cerebral atrophy [Figure 3a-c].
