Progressive subcortical calcifications secondary to venous hypertension in an intracranial dural arteriovenous fistula

Abstract

Intracranial dural arteriovenous fistulas (dAVF) are acquired lesions, with the most commonly reported findings on CT haemorrhage or focal oedema. We describe a case of progressive subcortical calcification on CT secondary to venous hypertension from a high grade dAVF.
