Trichloroethylene is a widely-used industrial solvent that is absorbed through the digestive or respiratory tracts or cutaneously. It has a selective tropism for the cardiovascular and central nervous systems and may cause death due to cardiac arrest or neurological sequelae. We present the case of a 25-yr-old women who was exposed to trichloroethylene in the workplace for 18 months and who developed a disabling myoclonic encephalopathy. Non-toxicological causes were excluded. Although the exposure ceased, the disease progressed with thalamic and cerebellar involvement. The patient, who had only a partial response to symptomatic treatment, suffered severe limitations in the activities of daily living and was registered as permanently disabled due to a work-related disability.
