  • Abstract
  • Look Inside

Magnetic resonance images in some cases of amyotrophic lateral sclerosis (ALS) revealed abnormal signals in both the paraventricular white matter and in the posterior limbs of the internal capsule. We examined T2- and diffusion weighted MR images of these lesions in 18 cases of ALS.

There were symmetrical high-signal areas in the posterior limbs of the internal capsule in all of the cases. The high-signal areas in the internal capsule corresponded to the pyramidal tracts in the anato-mical atlas by Talairach.
