Figure 2.
MR examination from Case 1 obtained 10 days following initial presentation. Coronal FLAIR MR images (A,B) were obtained following contrast which demonstrate abnormal signal within multiple bilateral parietal and occipital lobe sulci (long arrows) consistent with leptomeningeal involvement. Pachymeningeal involvement is also present adjacent to the left parietal lobe (B, short arrow). As in Figure 1, note the vasogenic edema within the peri-atrial white matter related to the thalamic lesions (B, dashed arrow).
