Repeated MRI examinations showed more extensive signal changes in the frontal lobes, parietal lobes, right temporal lobes, corpus callosums, basal ganglias, and brainstem, resulting in multiple patchy and strip hypointense on T1-weighted imaging, isointense T2-weighted imaging, and hyperintense FLAIR imaging [Figure 1]d with a relatively small edema.
Magnetic resonance imaging (MRI) of the cerebrum revealed the hyperintensity in T2-weighted and fluid-attenuated inversion recovery (FLAIR) images of the frontal lobe, parietal lobe, right temporal lobe, corpus callosum, and the periventricular cerebral white matter [Figure 1]a.
A repeated diffusion weighted imaging at the local hospital revealed the larger hyperintensity of corpus callosum. Three days ago, the patient developed lower limbs weakness progressively and could not be able to walk unaided.
