Pediatric SUNCT Syndrome.

This report describes a 5-year-old male with sudden unilateral headache attacks (2-50 seconds) accompanied by conjunctival injection, lacrimation, and nasal congestion. The episodes occurred without a precipitating factor, never during sleep. Brain imaging was normal. The attacks resolved spontaneously within 5 months. This headache syndrome (short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing) was previously described in two other children aged 10 and 11.
