FIG 3. Follow-up axial MR images obtained 8 months after the initiation of treatment.
A, Nonenhanced T1-weighted image the right frontal lesion (arrowhead) shows signal intensity almost identical to that of the CSF. This finding indicates chronic gliotic changes.
B and C, Consequent contrast-enhanced T1-weighted images reveal the absence of enhancement.
D, Nonenhanced T1-weighted image at the convexity shows multiple, small, hyperintense cortical lesions due to cortical necrosis (arrowheads).
