Case report's neuroimages. Axial and coronal MRI with T1 (a), FLAIR (b), diffusion (c), and contrast-enhanced T1, (d) weighted images show various predominant white matter (nodular and confluent) lesions hypointense on T1, hyperintense on T2 (not shown), and FLAIR. With diffusion restriction, some of them had fewer signals at the center (black arrow). After gadolinium administration, most of the lesions have mild incomplete annular enhancement (white arrowhead). MRI : magnetic resonance imaging; FLAIR : fluid-attenuated inversion recovery.

MRI reported white matter demyelinating lesions, mainly affecting the centrum semiovale, the frontal lobe, and the left parietal lobe; hypointense on T1-weighted images, hyperintense on T2-weighted images and fluid-attenuated inversion recovery (FLAIR) weighted images, DWI with restricted diffusion, and a parietal ring-enhancing lesion after IV gadolinium administration (Figure 1).
