FIG 3. MR imaging in patient 3 obtained 10 days after the onset of symptoms.

A, Spin-echo image (2500/80/1) of the brain demonstrates swelling and T2 prolongation in the cingulate gyri and the right insular cortex (arrowheads).

B, Coronal fluid-attenuated inversion recovery image (10,000/140/2200) image shows hyperintense lesions in the right cingulate gyrus and bilateral insulae (arrowheads), with foci of hyperintensity in the left cerebral white matter.

C, Apparent diffusion coefficient map reveals reduced diffusion in the bilateral cingulate gyri, in the entire right insular cortex, and in the most anterior aspect of the left insular cortex.
