There are three headaches syndromes that are typically characterized by strictly unilateral and always same-sided attacks: cluster headache, "cervicogenic" headache, and chronic paroxysmal hemicrania (CPH). In rare cases, cluster headache also occurs bilaterally; "cervicogenic" headaches probably as well. We present a patient with a probable bilateral CPH. To our knowledge no such case has prev...

Cluster headache (CH) is estimated to be the most common primary trigeminal autonomic headache, although it is a rare disabling medical condition. Dominant symptoms of CH include severe unilateral orbital, supraorbital, and/or temporal pain, lasting from 15 to 180 minutes if untreated, associated with at least one of various autonomic symptoms during the headache, such as conjunctival injection...

This headache type has had many different names in the past including ciliary neuralgia, erythroprosopalgia of Bing, hemicrania periodic neuralgiforms, histaminic cephalalgia, Horton’s headache, migrainous neuralgia, Sluder’s neuralgia, and sphenopalatine neuralgia. Kunkle and colleagues observed the tendency of the headaches to cluster in time and proposed the term, “cluster headache,” in 1952.

The case of a man with a 34 year history of episodic cluster headaches is described. At the peak of a cluster the headaches occurred up to twenty times a day. The headaches were unresponsive to conventional therapy but were dramatically abolished by indomethacin. This effect of indomethacin was confirmed in a double-blind placebo-controlled trial.
