Basilar artery ectasia demonstrated by computed tomography.
Basilar artery eclasia was demonstrated by computed tomography (CT) in 4 cases. The course and diameter of the basilar artery as seen by CT closely approximated those aspects of the artery visualized by angiography. The clinical manifestations of basilar ectasia correlated with what brain stem structures were impinged upon by the ectatic artery.
