Dural arteriovenous malformations in the anterior cranial fossa.

Two elderly patients with dural arteriovenous malformations in the anterior cranial fossa are reported. These patients experienced rupture of the malformations at the age of 73 and 87 years. Surgical excision of the malformation was carried out on the younger patient. In the other case megavoltage x-ray therapy was applied because radical operation was not prudent. A search of the literature provided 26 other cases of this malformation involving the anterior cranial fossa. These are the first cases of rupture of arteriovenous malformation in the anterior fossa in patients over the age of 70.
