Successful management of a symptomatic fusiform dilatation of the internal carotid artery following surgery of childhood craniopharyngioma.

INTRODUCTION: The development of fusiform dilatation of internal carotid artery is one of the vascular complications that can follow surgery for craniopharyngioma and other suprasellar tumours in children, but its pathogenesis and the line of management are still controversial. CASE REPORT AND DISCUSSION: We report a child who presented with a giant fusiform aneurysm involving the supraclinoid portion of the internal carotid artery after total removal of a craniopharyngioma and review the literature on related cases. The treatment of this phenomenon and its possible pathogenesis are discussed.
