Atypically located cluster headache.

Cluster headache (CH) is characterized by attacks of strictly unilateral, severe pain with orbital, supraorbital, or temporal location. They are accompanied by ipsilateral cranial autonomic features. Typical characteristics are short duration; pain occurring on one side of head, including eye area; and extreme intensity.[1] Pathophysiology of CH is not fully understood. [2] The pain almost always manifests itself in the same location during each attack. In this report, an atypically located CH is presented.
