Normal CT brain


The CT brain is normal. This is not unusual in headache and CT should really only be used for investigation in headache where there are red flags to suggest a cause that requires urgent treatment (most causes that require treatment will be seen on a CT and CT is ubiquitous, quick and available):

  • acute onset (worst headache ever)
  • focal neurology
  • nausea and vomiting
  • reduced conscious level
