title: A girl with headache, confusion and green urine.
abstract: The case of a 17-year-old girl with a history of headache, blurred vision, confusion, ataxia and syncope is presented. On admission, she had already recovered except for a slurring of speech. Her urine was found to be green. Screening for illegal drugs was negative, but gas chromatography with subsequent mass spectroscopy (GC-MS) revealed an extremely high concentration of flupirtine.
