Abstract
A 36-year-old man was suffering from brief, unilateral and short-lasting pain attacks always associated with marked homolateral tearing and conjunctival injection, both presenting in a cluster fashion. An arteriovenous malformation was subsequently discovered in the homolateral cerebellopontine angle. The clinical picture shares similarities with both cluster headache and trigeminal neuralgia, although it can not be accurately placed with either of these forms. Patients with similar symptoms have previously been described in detail, and on the basis of these few descriptions a new syndrome “short-lasting” unilateral neuralgiform headache attacks with conjunctival injection, tearing, sweating, and rhinorrhoea has been postulated. Assuming the validity of this syndrome as an entity, this case is in all probability its first “symptomatic” example. Careful evaluation of the varieties of cluster headache and trigeminal neuralgia, and the reporting of similar new cases as they arise are necessary to establish the nosologic boundaries of this syndrome.
