Case 1.
A, Axial FLAIR image (9264/150/2; TI = 2200) shows increased signal intensity of the white matter of the precentral gyri, which are atrophic (arrowhead).
B, Coronal FLAIR image (9264/150/2; TI = 2200) shows the hyperintensity limited to the upper part of the motor cortex (arrows) and extending across the corpus callosum (arrowheads).
C, Midline sagittal turbo spin-echo T2-weighted image (5422/110/2) shows thin, slightly hyperintense isthmus of the corpus callosum (arrow).

Case 2. Selected proton MR spectra (PRESS, 1500/136/1; nominal voxel size, 2 cm3) from the voxels indicated on the scout spin-echo T2-weighted MR image (2000/90/1; thickness, 10 mm) show moderate choline elevation (3.2 ppm), mild NAA loss (2.02 ppm), normal creatine peak (3.0 ppm), and an abnormally elevated peak at 3.6 ppm (myo-inositol) in the centrum semiovale. Spectra from the parasagittal cortical gray matter show only mild NAA loss. Similar proton MR spectroscopic findings in the centrum semiovale were found in case 1
- fig 3.
Case 4.
A and B, Coronal T2-weighted images (3648/99/2) of adjacent sections, A posterior to B, show nearly symmetrical involvement of the corticospinal tract from the cortex (A) to the brain stem (B) (asterisks).
C, Axial T2-weighted image (2100/90/2) at pontine level shows symmetrical pyramidal involvement (arrowhead).
