The evolution of platelet count, lactate dehydrogenase, and kidney function is illustrated in Figure 1.
Magnetic resonance (MR) work-up: four T2-weighted axial transverse views. Upper row: views from examination dated June 13 (day 13); lower row: similar slice locations in July 7 (day 37). a Symmetrical and linear abnormally increased signal intensity along the medial border of the globi pallidi (arrows). b Slightly more caudal slice than previous view revealing symmetrical hyperintense signal changes (arrows) involving the whole lenticular nuclei (globi pallidi + putamina). c, d Electronically co-registered views allowing comparison between slices in strictly similar location (a with c and to b with d) demonstrated complete subsidence of the abnormal signal intensities 3 weeks later.

On day 37, a follow-up brain MRI showed normalized brain status with complete subsidence of abnormal signal intensity changes (Fig. 2c, d) when compared to initial MR examination.
