title: A new variant nummular headache: large diameter accompanied with bitrigeminal hyperalgesia and successful treatment with carbamazepine.
abstract: Nummular headache (NH) is defined as a focal head pain that is exclusively felt     in a small area, which is typically 1-6 cm in diameter. Neurological     examinations are normal in all patients, but this report describes a new     variant. A patient was identified who presented with focal head pain that was     approximately 8 cm in diameter and bitrigeminal hyperalgesia on neurological     examination. Treatment with carbamazepine provided significant analgesic relief     in terms of both the frequency and intensity of pain. The findings enlarge the     clinical diversity of this headache disorder. The pathogenic mechanisms of NH     may be similar to trigeminal neuralgia in particular patients.
