Abstract:
:A 57-year-old male presented with a frontal bone defect associated with a middle meningeal arteriovenous fistula (AVF) manifesting as headache. The patient had a history of head injury 19 years previously. Skull radiography and computed tomography demonstrated a left frontal bone defect. Left external carotid angiography demonstrated a middle meningeal AVF at the frontal region, at the same location as the bone defect. The AVF was fed by the bilateral middle meningeal and left deep temporal arteries, and drained by the superior sagittal and ipsilateral cavernous sinuses. The minor feeding artery, the left deep temporal artery, was embolized with polyvinyl alcohol particles, then 0.4 ml of a 1:3 mixture of n-butyl cyanoacrylate and lipiodol was injected from the left middle meningeal artery. Follow-up angiography 3 months after the embolization revealed complete obliteration of the fistula. The bone defect may have been caused by erosion of the frontal bone by the pulsating effect of the feeding and draining vessels of the fistula, or by inadequate nutrition to the bone tissue because of the arteriovenous shunt.
