Dural arteriovenous anomaly fed by ethmoidal arteries.
A case of arteriovenous anomaly of the left ethmoidal groove, exclusively fed by both ophthalmic arteries and draining into the anterior segment of the superior sagittal sinus through a dilated bridging vein of the prefrontal cortex, is reported. Onset of symptoms was with an acute spontaneous intracerebral hematoma. The relation of this anatomo-clinical entity to other intracranial dural arteriovenous lesions is discussed, as well as its pathophysiology and its surgical management.
