Cluster Headache in 2-Year-Old Polish Girl

Cluster headache (CH) is one of the most severe types of primary headache. Intense, unilateral pain in orbital, supraorbital and/or temporal location accompanied by autonomic symptoms is the most characteristic feature. Diagnostic criteria for CH described in the International Classification of Headache Disorders (ICHD), 2nd edition are very helpful in clinical practice and prevent misdiagnosis of this rare type of headache (1). However, diagnosis of CH in the youngest patients is very troublesome due to the lack of patient cooperation. Thorough case history taking and careful parental observation of the child’s behaviour during attacks are crucial in the diagnosis of this type of headache. The patient reported in this paper is one of the youngest with well-documented early childhoodonset CH.
