We report a new case of short-lasting, unilateral, neuralgiform headache attacks with conjunctival injection and tearing (SUNCT). This rare headache, described in 1978, shares clinical traits with trigeminal neuralgia and cluster headache and its diagnostic classification as a unilateral headache with autonomic involvement has been the subject of considerable debate. The etiology of SUNCT is unknown, although it is considered a highly difficult pain to treat. We discuss our patient's symptoms and response to treatment with carbamazepine.
