Transellar intercavernous carotid anastomosis with agenesis of internal carotid artery and right-sided descending aorta: case report.
We report a patient with a transellar intercavernous carotid anastomosis associated with right-sided descending aorta and agenesis of the internal carotid artery. To our knowledge, such an association has not been reported previously. Findings at angiography, computed tomography (CT) and dynamic CT are presented. We suggest that dynamic CT is not a reliable method of excluding this anomaly, a fact that has relevance to investigation prior to transphenoidal surgery for pituitary adenoma.
