title: Spontaneous acute subdural hematoma: A rare presentation of a dural intracranial fistula.
abstract: Dural arteriovenous fistulas are acquired lesions between the meningeal arteries and their associated draining veins. They may have highly variable clinical presentations and evolution, from severe neurological deficit to no or trivial symptoms. Intracranial hemorrhage occurs in less than 24% of all dural fistulas, and the bleeding is usually subarachnoid, more infrequently intracerebral, and rarely in the subdural space. Here, we present a rare case of a patient who presented with a subdural spontaneous hemorrhage. After investigation by cerebral angiography, the diagnosis of a dural arteriovenous fistula was made. The patient underwent uneventful endovascular treatment. As there are with only a few reports in the literature of such a presentation, we present this patient and perform a brief review of the literature.
