FIG 1. Axial T2-weighted (2900/85/2 [TR/TE/NEX]) images in a 16-year-old patient who had inhaled toluene for 6 years.

A, High signal intensity is seen in the centrum semiovale (arrows) on both sides. The peripheral cerebral white matter and gray matter-white matter differentiation are preserved.

B, High-signal-intensity changes involve the frontal and parietal periventricular white matter (arrowheads). The pattern of white matter changes is compatible with that of the restricted type. Note that the lateral ventricles and cerebral sulci are enlarged.
