Abstract

Arteriovenous malformations (AVM) are rare, and scalp AVM comprises only 8.1% of all AVM. Scalp AVM may present with headache, local pain, and tinnitus. It may also remain clinically silent until a bleeding episode ensues. We report the case of a 29-year old male with an extremly large scalp AVM in the right temporoparietal region. We initially wanted to do conventional angiography to map the nidus, identify the feeders, and plan for a preoperative embolization. Our patient needed prompt surgery to control an episode of profuse bleeding coming from the mass before a conventional angiography could be done. The surgery incurred a significant amount of blood loss, and a non-resectable mass was left after the procedure. We were able to successfully perform serial embolization of a part of the the patient’s AVM two years after the surgery.
