title: Is hemicrania continua a single entity or the association of two headache forms? Considerations from a case report.
abstract: Hemicrania continua (HC) belongs to the group of primary headaches and it is characterized by a strictly unilateral, continuous headache of moderate intensity, with superimposed exacerbations of severe intensity that are accompanied by trigeminal autonomic features. The syndrome is completely responsive to indomethacin. Here we report a case of a 49-year-old man with HC, which may be viewed as a combination of different types of headache, ie, chronic tension-type headache and trigeminal autonomic cephalalgia. The analysis of this case raises interesting issues regarding the proper place of HC among the primary headache forms.
