Abstract

Acquired unruptured dural arteriovenous fistulas (DAVFs) have been described; however, ruptured de novo DAVFs remain exceedingly rare. We describe the case of a man in his 40s who presented with a recurrent intraparenchymal haemorrhage several years after angiographic cure of an intracranial arteriovenous malformation (AVM). Repeat angiography identified a new Cognard type IV DAVF anterior to the prior craniotomy. He underwent preoperative embolisation followed by craniotomy to completely obliterate the fistulous point. This case illustrates the need for close monitoring of AVM patients, even after complete obliteration, as local recrudescence of arteriovenous shunting can occur even in adulthood.
