title: A fatal case of spongiform leukoencephalopathy linked to "chasing the dragon".
abstract: BACKGROUND
  "Chasing the dragon" involves placing heroin on aluminum foil, heating it from below with a flame, and inhaling the pyrolysate through a straw. It has rarely been associated with the development of a progressive spongiform leukoencephalopathy.
  
  
  METHODS
  A 43-year-old woman presented with 2 weeks of bizarre behavior, forgetfulness, and slowed speech and movements. Serum, cerebrospinal fluid, and head computed tomography (CT) scan were normal. The patient progressed to coma and expired during week 4 of hospital admission. The family confirmed that she "chased the dragon." Cause of death at post mortem examination was spongiform leukoencephalopathy.
  
  
  CONCLUSIONS
  The diagnosis of heroin pyrolysate-induced spongiform leukoencephalopathy should be considered in a patient with a history of "chasing the dragon" and neurobehavioral changes, including confusion, apathy, cerebellar signs, and motor restlessness.
