Brain MRI according to sagittal T1 (a), sagittal FLAIR (b), axial T2 (c) and
axial T1 with Gadolinium injection (d) showing small lesions in corpus
callosum (a; arrowhead) in hypersignal FLAIR including in the midbrain (b;
arrows), periventricular (c) with no contrast enhancement at gadolinium
injection (d).

In light of this clinical presentation, a Susac syndrome was evoked (Figure 1(a)-(d)).
Second brain MRI performed in front of worsening symptoms showing extensive
increased size and number lesions with the same characteristics on sagittal
T2 (a; arrows) and coronal FLAIR (b; arrowhead)-weighted images, some of
which with a restriction on diffusion-weighted images (c; arrows) and with
no abnormalities at angiographic sequences (d, e).
