Silent Tumefactive Demyelinating Lesions and Radiologically Isolated Syndrome

Figure 3

One year later. (a) Regression of tumefactive lesions is evident. (b) Axial fluid attenuation inversion recovery (FLAIR) image shows new hyperintense lesions in the bilateral parietooccipital white matter. (c) Sagittal FLAIR image demonstrates periventricular, cortical/juxtacortical demyelinating lesions. (d) T1-weighted postcontrast image shows contrast enhancement of the lesion in the left parietooccipital white matter.
