Initial magnetic resonance images. (a) Multiple bilaterally asymmetrical,
poorly marginated T2 high-signal-intensity foci, juxtacortical and
subcortical foci in bilateral frontal, left temporal, and occipital lobes,
as well as in bilateral basal ganglia. (b) Similar T2 high-signal-intensity
foci in the right periventricular region. (c) T2 high-signal-intensity foci
involving the bilateral cerebral peduncle of the midbrain. (d) Short-segment
T2 high-signal-intensity foci of spinal cord at the C6-C7 level.

Follow-up magnetic resonance imaging after 3 months. (a) FLAIR axial scan at
the level of the body of lateral ventricle displaying high-signal-intensity
lesions in the right periventricular region. (b) T2 axial scan at the same
level. (c) Coronal T2 scan displaying foci of high signal intensity in the
right periventricular region and juxtacortical area of the left frontal
lobe.

FLAIR (Fluid-attenuated Inversion Recovery) axial scan (Figure 2(a)) and T2 axial scan (Figure 2(b)). Foci of high signal intensity in the right periventricular region and juxtacortical area of the left frontal lobe were seen in a T2 coronal scan (Figure 2(c)).
Comparison of the initial MRI (a and b) to the follow-up MRI after 3 months
(c and d). (a and b) T2-weighted axial images at the level of basal ganglia
and body of the lateral ventricle. (c) T2-weighted axial image at the level
of basal ganglia and body of the lateral ventricle. (d) FLAIR image at the
level of basal ganglia and body of the lateral ventricle.

Compared to the previous scan, the size and number of signal intensities were decreased (Figure 3).
