Magnetic resonance imaging differential diagnosis of brainstem lesions in children

Figure 8 Vigabatrin-related transient magnetic resonance imaging abnormalities. A 8-mo-old infant shows symmetric and bilateral pontine lesions located at the central tegmental tracts (white arrows in panel A) and bilateral basal ganglia and midbrain (panel B) T2 hyperintensities. Diffusion weighted images showed net restriction of diffusion at the same sites (right upper inlets in panels A and B). The T2 signal alterations resolved after three months of vigabatrin withdrawal (panels C and D).
