Quick-lasting unilateral neuralgiform headache assaults with conjunctival injection and tearing (SUNCT) is a main headache syndrome with an unclear pathogenesis. Nonetheless, there may be rising proof within the literature for secondary SUNCT being attributable to sure recognized lesions. We explored the attainable neurobiological mechanism underlying SUNCT primarily based on all reported circumstances of secondary SUNCT for which detailed info is offered. Right here we report a case of neuromyelitis optica spectrum problems that had typical signs of SUNCT which may have been attributable to involvement of the spinal nucleus of the trigeminal nerve. We additionally assessment circumstances of secondary SUNCT reported within the English-language literature and analyze them for demographic traits, medical options, response to remedy, and imaging findings. The literature assessment reveals that secondary SUNCT can derive from a neoplasm, vascular illness, trauma, an infection, irritation, or congenital malformation. The pons with involvement of the trigeminal root entry zone was essentially the most generally affected area for inducing secondary SUNCT. In conclusion, the neurobiology of secondary SUNCT contains constructions such because the nucleus and the trigeminal nerve with its branches, suggesting that some circumstances of main SUNCT have underlying mechanisms which might be associated to current focal injury that can’t be visualized.
