title: Bilateral cortical blindness associated with carotid stenosis in a patient with a persistent trigeminal artery: case report.
abstract: A patient with findings of bilateral cortical blindness and a unilateral carotid bruit is reported. A persistent trigeminal artery allowed emboli from a unilateral ulcerated internal carotid plaque to affect the visual cortex bilaterally. The angiographic findings and a brief discussion of this anomalous artery are presented.
