Bilateral absence of the internal carotid artery with sellar enlargement due to anomalous vascularity.
A unique case is described in which a patient with a primary cerebral neoplasm was found to have bilateral aplasia of the internal carotid artery that presented with an eroded sella turcica mimicking an intrasellar mass. The embryologic origin of this anomaly is discussed, and the literature is reviewed.
