A rare case of intracerebral hemorrhage due to arteriovenous malformation located at petrous portion of the temporal bone

Abstract

Primary intraosseous arteriovenous malformations (AVM) are not infrequently encountered. We report a case of intraosseous arteriovenous malformation arising in the left temporal bone. A 51-year-old male patient presented with loss of conscious. Computerized tomography displayed hematoma measuring 4 cm in diameter in the left temporal lobe. Digital subtraction angiography (DSA) showed that a temporal bone AVM supplied by all the branches of the external carotid artery and vertebral artery. Many treatment modalities can be considered for preoperative steps and/or for definitive treatment. We preferred embolisation for this vascular pathology. To the best of our knowledge this represents the first case of an intraosseous arteriovenous malformation located in the temporal bone.
