- Abstract: Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by thunderclap headache and multiple reversible intracranial vasoconstrictions. Here we report a case of RCVS after exposure to ethylene oxide (EO) gas, which is a widely used sterilant. A 34-year-old woman presented with aphasia, right-arm weakness, and severe headache after inhaling EO gas. Brain imaging revealed multiple infarcts and multiple intracranial stenoses. The stenotic lesions completely regressed on follow-up CT angiography. This is the first report of RCVS after exposure to EO gas.
