We report 2 cases of tentorial dural arteriovenous fistula.
Case 1: A 37-year-old man presented with severe headache. Neurological examination was normal. MR images demonstrated a round dilatated Galenic vein. But MR images showed no intracranial hemorrhage or congestive edema. Angiograms showed a tentorial dural arteriovenous fistula with a dilatated Galenic vein. Initially, we embolized the dural arteriovenous fistula using a transarterial approach. For residual dural arteriovenous fistula, gamma knife radiosurgery was performed. After 2 years and 5 months, angiographic cure was obtained and the postoperative course was uneventful.
Case 2: A 70-year-old woman presented with pulsatile tinnitus and headache. Neurological examination was normal. MR images demonstrated a varix near the Galenic vein and showed no intracranial hemorrhage or congestive edema. Angiograms showed a tentorial dural arteriovenous fistula. For dural arteriovenous fistula, gamma knife radiosurgery was performed. After 4 years, angiographic cure was obtained and the postoperative course was uneventful.
We discuss the clinical features and the management of these 2 cases.
