158 Chapter 5 Figure 2. Examples of MRIs MRI of the brain at the level of the basal ganglia with axial T2-weighted sequences (A, D), diffusion-weighted imaging (B, E) and matching ADC maps (C, F) of two different patients. Patient 1 (A, B, C) shows hyperintense T2 signal and diffuse swelling of the cortex of all the cerebral lobes and the basal ganglia (A) with corresponding restricted diffusion in the affected areas (B, C) (extensive cortex/white matter injury). Patient 2 (D, E, F) demonstrates hyperintense T2 signal of the basal ganglia and thalami and focal swelling of the cortex of the occipital lobes (D) with corresponding restricted diffusion in the affected areas (E, F) (focal cortex/white matter injury with deep grey matter involvement).
