BRIEF REPORT SUNCT syndrome treated with gamma knife targeting the trigeminal nerve and sphenopalatine ganglion

SUNCT syndrome, an abbreviation for short lasting-uni-lateral neuralgiform headache attacks with conjunctival injection and tearing is one of the most debilitating uni-lateral headache syndromes often refractory to medical therapy [1]. We report a case of a 50-year-old man diag-nosed with refractory SUNCT syndrome having a near complete response to gamma knife surgery targeting the trigeminal nerve and sphenopalatine ganglion.
