Prognosis is poor with fatal outcome within 1 year in 90% of patients. Our case report shows that diffusion tensor imaging can give early and specific information about disease status and extent in a 15-year-old girl with progressive multifocal leukoen...
We report the clinical, MR imaging, and proton MR spectroscopy findings in a middle-aged woman with proved methadone-induced toxic leukoencephalopathy. The imaging characteristics of this unusual condition have been reported only rarely in the medical literature. We show that the imaging findings in methadone-induced toxic leukoencephalopathy are similar, though not identical, to previously rep...
