FIG 1. Patient 1 presented with nonfluent aphasia and bilateral upper-extremity weakness.
A, Axial DW image is limited by motion artifact. Areas of restricted diffusion in the centrum semiovale account for the arm weakness. Nonfluent aphasia may be subcortical.
B, Axial FLAIR image obtained 39 months later shows minimal abnormal T2 signal intensity consistent with demyelination. There are no residual neurologic deficits.
