A 26-year-old female patient referred to our emergency service with complaint of increase headache and swelling of the left upper eye led. External examination of the head revealed left frontal scalp and left eye led swelling, which was soft and pulsatile. Brain computed tomography (CT) scan and magnetic resonance imaging showed left frontal soft tissue and left periorbital swelling with crowded left intraorbital contents. Brain CT angiography showed vascular mass lesion in the left frontal subcutaneous lesion. Six-vessel cerebral angiography showed left frontal scalp arteriovenous malformation (AVM) supplied from the right and left superficial temporal arteries from the external carotid artery and from the left supraorbital artery arising from the ophthalmic artery of the internal carotid artery. By endovascular technique, bilateral superficial temporal arteries were occluded with Onyx 18 (Micro-Therapeutics, Inc., Irvine, CA). The patient was operated after 2 days. Left eye-brow incision was performed and the supraorbital artery was exposed, ligated, and cut. Left fronto-temporal skin incision was performed and the AVM totally excised. No intraoperative nor postoperative complications seen. Follow-up cerebral angiography showed total resection of the AVM.
