%0 Journal Article %A M Bergui %A G B Bradac %T Uncommon symptomatic cerebral vascular malformations. %D 1997 %J American Journal of Neuroradiology %P 779-783 %V 18 %N 4 %X 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. %U https://www.ajnr.org/content/ajnr/18/4/779.full.pdf
