Two months later, the hyperintense lesions located in the bilateral periventricular white matter (arrow), body of the corpus callosum (arrow), and right periaqueductal grey matter (arrowhead) were increased in number and size, as observed on T2-weighted images. After gadolinium contrast injection, more prominent ring and incomplete ring enhancement over these lesions is noted on the T1-weighted image (curved arrows). In the sagittal view, multiple sclerosis plaques with an increased number of Dawson’s fingers are noted (black arrow).
