Dural arteriovenous fistulas are rare acquired vascular lesions that may cause intracranial haemorrhage. Angioarchitectural features, particularly the presence of cortical venous drainage, influence their clinical natural history with a distinction of “benign” versus “aggressive” lesions. We describe a very rare case of cranial dural arteriovenous fistulas without cortical venous drainage with an haemorrhagic onset spontaneously disappearing in two weeks, together with a discussion of the possible physiopathological mechanisms.
