Abstract
BACKGROUND: Short-lasting unilateral neuralgiform headaches include those with conjunctival injection and tearing and with cranial autonomic symptoms. Most frequently reported as idiopathic, there is a growing number of symptomatic cases described.
CASE REPORT: A 57-year old man presented a 16-year history of right hemifacial short-lasting pain attacks accompanied by ipsilateral autonomic symptoms and simultaneous malar contractions. Brain MRI disclosed a right acoustic neuroma compressing the right facial nerve and a venous developmental anomaly perpendicular to the right facial nerve root entry zone, without lesions affecting the trigeminal nerve. He was started on lamotrigine, resulting in complete remission of pain attacks, autonomic signs and facial contractions.
CONCLUSIONS: This patient presents a typical short-lasting unilateral neuralgiform headache with response to lamotrigine. The uniqueness of the case is the co-occurring malar contractions, evocative of facial nerve involvement. We speculate whether facial nerve compression renders this nerve more susceptible to triggering during a short-lasting unilateral neuralgiform headache attack.
