Dolichoectasia of the cerebral artery, a rare disorder of arterial elongation, dilatation, and tortuosity, usually involves the vertebrobasilar system in elderly patients with hypertension and is associated with the development of atherosclerosis in the aging process. We present a very rare case in a 17-year-old girl with multiple sclerosis of dolichoectasia of the supraclinoid segment of the internal carotid artery that was found incidentally on magnetic resonance angiography and seems to represent a congenital arterial malformation.

大脑动脉迂曲扩张，是一种罕见的动脉延长、扩张和迂曲病症，通常累及老年高血压患者的椎基底系统，并与衰老过程中动脉粥样硬化的发展相关。我们报告了一例极为罕见的病例，一名17岁患有多发性硬化症的女孩，其颈内动脉床突上段迂曲扩张，这是在磁共振血管造影时偶然发现的，似乎代表一种先天性动脉畸形。
