General dysplasia of the cerebral arteries with persistent primitive acoustic artery and giant aneurysm.

A case of cerebrovascular systemic dysplasia is presented. The anomalies were: persistent primitive acoustic artery, giant aneurysm of the left internal carotid artery, aneurysm of the basilar artery, and an arteriovenous fistula. A review of the literature shows that the association of multiple malformations of cerebral vessels with a persistent primitive acoustic artery has not previously been described. Impairment of embryonic development is suggested as the origin of the malformations.
