Figure 1

The first row shows brain MRI (from left to right, DWI, FLAIR, and T1+C) from first ER visit with presumed TGA: arrows show subtle signal changes that were too mild to be called. The middle row shows brain MRI (from left to right, DWI, FLAIR, and T1+C) six weeks from his first presentation: signal changes in DWI, FLAIR in hippocampus; moreover, there is enhancement in hippocampus and medial temporal lobe. The lowest row shows that brain MRI after treatment shows subtle improvement in hippocampus and temporal areas.
