Case Study
A rare case of de novo formation of dural and osteodural arteriovenous fistulas after encephalitis is presented. We review and discuss the etiological angiogenetic factors and processes in intracranial dural arteriovenous fistulas formation. Local tissue hypoxia may have played a role in the initial step causing sprouting angiogenesis as the main pathogenesis of DAVFs formation.
