Figure 1:
(A) MRI brain T2-weighted sequence revealed T2 hyperintensity in the bilateral cingulate gyri (white arrow) and insula cortices (arrowhead). (B) DWI sequence showed hyperintensity in the same distribution as the T2 hyperintensitiy in (A).
Figure 2:
Figure 2:
ADC image showed corresponding ADC reduction in regions with DWI hyperintensity as previously seen in Fig. 1B.
