ABSTRACT
Short-lasting unilateral Neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) is a rare form of primary headache disorder. SUNCT-like syndrome or secondary SUNCT has been also described in the literature. We report the first case of SUNCT syndrome in a patient with a previous diagnosis of small cell lung cancer. Brain magnetic resonance imaging of this pa-tient revealed a lesion located in the right temporal muscle. He had a moderate response to the treatment with carbamazepine. SUNCT-like syndrome diagnosis should be evaluated carefully in patients with previous history of lung cancer. Cranial metastases may be a trigger for this headac-he syndrome, and cranial MRI is needed in investigating secondary SUNCT in these patients.
