Evaluation of bleeding risk in dural arteriovenous fistula using susceptibility-weighted imaging: A case report

Susceptibility weighted imaging (SWI) is a new imaging modality for the detailed depiction of cerebral venous hemodynamics. We report a case of a dural arteriovenous fistula (dAVF) in which a symptomatic intracranial hemorrhage occurred at the lesion site where previously performed SWI showed marked...

Description
Summary:Susceptibility weighted imaging (SWI) is a new imaging modality for the detailed depiction of cerebral venous hemodynamics. We report a case of a dural arteriovenous fistula (dAVF) in which a symptomatic intracranial hemorrhage occurred at the lesion site where previously performed SWI showed marked hypointensity. Previous reports about SWI findings in patients with dAVF have focused on their correlations with angiography and there has been no report mentioning the direct relationship of SWI finding and the risk of dAVF bleeding. This case shows the possibility that SWI might be useful for estimating the bleeding risk.
