Refractory short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing responsive to anti-calcitonin gene-related peptide monoclonal antibodies: A case report

Background: Short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) is a rare but severely disabling variant within the spectrum of trigeminal autonomic cephalalgia lacking evidence-based treatment. Case: We report a case of chronic SUNCT in a 67-year-old man refractory to various guideline-conforming treatment attempts responding excellently to galcanezumab. Conclusions: This case report indicates that monoclonal antibodies against calcitonin gene-related peptide, specifically galcanezumab, might be a treatment option for SUNCT warranting further investigation.
