MRI in chronic toluene abuse
We present two Japanese men with a more than 10-year history of toluene inhalation. In one patient with severe neurological impairments, T2-weighted MRI images showed symmetrical high-signal areas in the posterior limbs of the internal capsules, cerebral white matter, and cerebellar peduncles. There were bilateral reduced intensity areas in the thalami, basal ganglia, and cerebral cortex. Signal intensity changes of the other patient were mild; reduced intensity of the brain cortex has not been reported previously.
