FIG 3. Images of Patient 5, a 35-year-old woman with chordoid glioma.
A, Axial T1-weighted spin-echo MR image (450/20) reveals an isointense hypothalamic/third ventricular mass (arrows).
B, Axial fluid-attenuated inversion recovery MR image (8912/142; inversion time, 2200 ms) reveals an iso- to slightly hyperintense hypothalamic/third ventricular mass (large arrow). Note vasogenic edema within the basal ganglia (small arrows), posterior limbs of the internal capsules, and lateral geniculate ganglia of the thalami (arrowheads).
C, Axial fluid-attenuated inversion recovery MR image (8912/142; inversion time, 2200 ms) obtained at a level approximately 1.5 cm inferior to that shown in B. Note splaying of the cerebral peduncles (large arrows) and bilateral involvement of the optic tracts (small arrows).
