FIG 2. Images show cranial extension to symmetrically involve bilateral thalami, hippocampi, basal ganglia, and the dorsal aspect of the brainstem.
A, T2-weighted MR image of the brain, obtained at the level of basal ganglia, reveals hyperintensity of the caudate head and lentiform nucleus.
B, T2-weighted MR image of the brain, obtained at the level of the pons, reveals hyperintensity of the posterior portion of the pons.
