title: Atypical presentations of cluster headache.
abstract: Recently, cluster headache has been shown to occur with aura, suggesting that as more cluster patients are seen by headache specialists new forms of this well-defined primary headache syndrome will be identified. This study presents three atypical presentations of cluster headache: persistent or unremitting cluster, periodic cluster, and reflex or event-related cluster. Case reports are presented with an explanation as to why these headaches should be considered cluster headache.
