title: Dural arteriovenous malformation near the left sphenoparietal sinus.
abstract: The case of a 14-year-old boy with a dural arteriovenous malformation in the region of the sphenoparietal sinus associated with a markedly dilated dural sinus is reported. The arterial supply was solely via the meningeal branches of the left external carotid artery; venous drainage was through dilated venous channels into the superior ophthalmic vein and pterygoid venous plexus. Treatment consisted of artificial embolization and ligation of the left external carotid artery and excision of the dilated venous sac. The vascular lesions were absent from the post-operative angiogram, except for small angiomatous remnants fed by meningeal branches of the left internal carotid artery.
