A case of cardiovascular collapse after gas encephalography is presented. It draws attention to a previously unreported danger connected with the use of nitrous oxide or a mixture of nitrous oxide and oxygen as a contrast medium in encephalography. The rapid elimination of nitrous oxide may lead to a deleterious decrease in cerebrospinal pressure in patients with large cerebral ventricles.
