case_images: Magnetic resonance imaging of the brain: Diffusion-weighted sequences during 2010 episode (a-d) showing restricting lesions in left posterior limb of internal capsule and splenium of the corpus callosum. Lesions involving bilateral subcortical white matter and centrum semi ovale (e-h) during July 2013 episode. Resolution of the changes (i-l) in the repeat imaging done after 1.5 months. Arrows showing abnormalities

case_images: He was evaluated with a magnetic resonance imaging (MRI), which showed T2 hyperintense diffusion-restricting lesions in the splenium of the corpus callosum and internal capsule [Figure 1a-d]. Imaging with MRI July showed bilateral periventricular and centrum semiovale diffusion restricting lesions [Figure 1e-h]. Serial imaging with MRI of the brain revealed T2 hyperintense signal changes in posterior limb of bilateral internal capsule (left > right) and splenium of corpus callosum in 2010; these were diffusion-restricting [Figure 1a-d]. In July 2013, MRI July revealed T2 hyperintense, T1 isointense diffusion-restricting lesions in bilateral centrum semi ovale and internal capsule [Figure 1e-h]. Repeat MRI in August 2013 in our hospital showed disappearance of the centrum semi ovale lesions [Figure 1i-l].
