RT Journal Article SR Electronic T1 Uncommon symptomatic cerebral vascular malformations. JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 779 OP 783 VO 18 IS 4 A1 Bergui, M A1 Bradac, G B YR 1997 UL http://www.ajnr.org/content/18/4/779.abstract AB We describe three cases of unusual vascular malformations in which the most relevant angiographic findings were the presence of a pathologic arteriovenous shunt through multiple small direct arteriovenous fistulas and the lack of a clearly identifiable nidus. All malformations were symptomatic. Such lesions are relatively rare, but they should be taken into consideration in the differential diagnosis of cerebrovascular malformations.
