Primary or idiopathic stabbing headache

The idiopathic or primary stabbing headache is presented with short duration, is poorly understead in children, is reported exceptionally under 5 years old, and probably under diagnosed. Four cases from a general paediatrician clinic are presented, with age between 2 and 5 years. The crisis lasted less than 5 minutes, with variable intensity, and with vomiting in one patient. All presented familial history of migraine. Systemic work-up was normal. At the beginning, all received another diagnostic. The headaches disappeared between 3 and 12 months, but migraine developed in 2 cases. One received paracetamol with uncertain response.
