[Cluster headache in a 3 year old child].
BACKGROUND
Cluster headache is a rare disorder in childhood. We identified, in the literature, 64 cases of cluster headache starting at or before 18 years (only 17 of them began before 10 years old). All patients met the criteria of the International Headache Society. Russell et al demonstrated recently that the cluster headache is an inherited disorder in some families. They conclude that the gene is present in 3 to 4% of males and 7 to 10% of females with cluster headache and that it has an autossomal dominant transmission.


METHODS
The authors report the clinical case of a five year old child with cluster headache starting at three years. This paper reviews the differential diagnosis and the treatment of cluster headache.
