Abstract
A 70-year-old man complained of two distinct types of unilateral headache during the past fifteen years. When the illness began, the pain was intermittent and short-lasting. In successive years, the crises appeared in clusters and lasted weeks to months. At present, the pain occurs daily, and is located on the right side, from the forehead supraorbitally to the temporal region. Some attacks last 30 sec and are accompanied by tearing, conjunctival injection, rhinorrhea and a subjective need to micturate. Other headaches last 1/2-1 h and are occasionally accompanied by local ipsilateral dysautonomic symptoms. Attacks of pain are provoked by movements of the trunk and neck. A vascular malformation in the right cerebellopontine angle was demonstrated on cranial CT and MRI, and by angiography.
