Dural arteriovenous malformations associated with cerebral aneurysms

Only limited information is available concerning dural arteriovenous malfor mations (AVMs) found in association with cerebral aneurysms. The present re port focuses on six such cases, concentrating attention on clinical charact eristics and significance. Of a total or 46 dural AVMs encountered over a g iven period, six (13%) were linked with cerebral aneurysms. Particularly st rong associations were noted for dural AVMs in the anterior cranial fossa ( three of four cases) and convexity (all of three cases). With dural AVMs in the anterior cranial fossa, subarachnoid haemorrhage is common, so that wh ere this is encountered the possibility of a complicating aneurysm should b e considered in order to select an appropriate treatment.
