title: Occlusion of the internal carotid artery by intracranial tumors.
abstract: Occlusion of the internal carotid artery by an intracranial tumor occurs only rarely. Three such cases are reported here. All were parasellar tumors, 2 meningiomas and 1 pituitary adenoma. The occlusion was demonstrated by carotid angiography in all cases. The location of the tumor was demonstrated by a computerized tomographic (CT) scan in 1 case. These 3 cases were encountered in a neurosurgical series of over 4,500 brain tumors and 10,000 angiographic examinations during the period 1952 to 1979.
