Anterior fossa dural arteriovenous malformation discovered by means of PW-Doppler examination

Abstract

One case of dural arteriovenous malformation in the base of the anterior cranial fossa is reported. It was discovered by means of a PW-Doppler examination of angular branch of the ophthalmic artery in a patient under observation for hypertrophy of a superficial temporal artery. The nidus was located in the region of the cribriform plate and fed by the anterior ethmoidal arteries of both sides, draining into the superior sagittal sinus, via pial enlarged veins. The patient successfully underwent surgical treatment and a post-operative PW-Doppler confirmed normalization of the flow pattern in the angular branches of both ophthalmic arteries.
