It is not often that a CT will be able to give you a hint to a toxicologic diagnosis. The following are CT findings that are either suggestive and even sometimes almost diagnostic for a given to toxin:

1) Intraparenchymal or Subarachnoid Hemorrhage: sympathomimetics or mycotic anuerysm rupture secondary to IV drug abuse

2) Basal Ganglia bilateral focal necrosis: characteristic of carbon monoxide, cyanide, hydrogen sulfide and even methanol

3) Severe advanced atrophy out of proportion for age: alcoholism, toluene
