Cerebral angiographic changes associated with tuberous sclerosis

Abstract

Two patients with tuberous sclerosis were examined angiographically. In one, direct left carotid angiography showed a contralateral shift of the anterior cerebral artery and lateral displacement of the middle cerebral artery. On the lateral series, increase in the sweep of the anterior cerebral artery as well as stretching of the opercular branches of the middle cerebral artery were noted in the early arterial phase. In the later arterial phase, there was marked hypervascularity, with the contrast substance temporarily pooling in small, rounded collections. In the mid-arterial phase of the second case, pooling of the the contrast medium within the tumor and many small, berry-like outpunchings were noted. There was no evidence of early venous drainage in either case.
