Intracranial dural arteriovenous fistulas are more common in men (80-85%). 10-15% of all intracranial vascular malformations are dural arteriovenous fistulas, and only 10% seem to be in the anterior fossa. Fistulas of the anterior cranial fossa are usually bilateral. Less frequently, the fistula is fed unilaterally from the anterior ethmoidal branches of the ophthalmic artery, and rarely by the posterior ethmoidal branches. Unusually, minor branches originating from the ophthalmic artery can also feed these fistulas. In more than 75% of the cases, drainage to the superior sagittal sinus through the frontal cortical veins is typical. Patients can be asymptomatic or present to the hospital with symptoms ranging from headaches, seizures, and ocular symptoms, to fatal bleeding. The incidence of hemorrhage is 79% and higher than the risk of bleeding associated with the other regions (15%). Current treatment options are resection, endovascular therapy, or stereotaxic radiosurgery. Anterior fossa dural arteriovenous fistulas tend to have a malignant drainage pattern. Due to their relationship with high bleeding and neurological morbidity, they should be treated regardless of whether they are symptomatic.
