INTRACRANIAL ARTERIOVENOUS MALFORMATIONS AND HEADACHE

Abstract

SYNOPSIS Twenty‐nine males and 19 females with intracranial arteriovenous malformation were questioned about migraine and headache. Fifteen (31.2%) had a long history of migraine, 23 (48%) suffered from other headaches, and 10 (20.8%) were headache free. The frequency of headache was similar to that in the general population, but the frequency of migraine was higher. Migraine was more common with small malformations when the malformation had bled or when it was occipital. Unilateral headache was nearly always on the side of the malformation. Thermography was asymmetric in 56%, the warm side coincided with that of malformation in 3/4 of these patients.
