Skull changes associated with intracranial arteriovenous malformations.

The roentgenographic changes in the skull seen in 61 patients with intracranial arteriovenous malformations are described. Gross enlargement of the internal carotid artery, venous sinuses and veins caused recognizable changes in roentgenograms of the skull. Thickening of the skull was sometimes associated with intracranial arteriovenous malformations. In some cases this involved the hemicranium on the side of the malformation and in others the cranial vault was thickened on both sides.
