Short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing syndrome secondary to an epidermoid tumor in the cerebellopontine angle.

Short-laSting unilateral neuralgiform headache attacks with conjunctival injection and tearing syndrome is a rare headache disorder classified under TAC. It is characterized by short-lasting unilateral attacks of severe neuralgiform pain associated with prominent lacrimation and redness of the ipsilateral eye. Other autonomic symptoms include nasal congestion, rhinorrhea, and eyelid edema.1 Although SUNCT syndrome is a primary headache disorder, it can be associated with secondary pathologies.1,7,14 We report on a patient with paroxysmal left retroorbital pain with associated autonomic symptoms of ipsilateral conjunctival injection and lacrimation, suggestive of SUNCT, secondary to an epidermoid tumor in the left CPA. The symptoms completely resolved after a retrosigmoid craniotomy and resection of the tumor. Case Report
