[Amphetamine-induced toxic encephalopathy].

In this case report, a 40-year-old woman presented with altered mentation, central facial palsy and hemiparesis. Acute CT scan showed several hypodense, rounded areas in both hemispheres. Urine toxicology tested positive for amphetamine. Subsequent cerebral MRI had hyperintense T2-weighted fluid-attenuated inverse recovery (FLAIR) lesions in both hemispheres, indicating demyelinating disease. A biopsy was made from one of the lesions. The final diagnosis was toxic encephalopathy.
