Dural arteriovenous malformation of the anterior cranial fossa occurring after bifrontal craniotomy.
A case of dural arteriovenous malformation of the anterior cranial fossa developing after bifrontal craniotomy is reported. The nidus was fed mainly by the left anterior ethmoidal artery. It was drained into the right sylvian vein and superior ophthalmic vein with patency of the superior sagittal sinus. A left frontal hemorrhage resulted from the nidus itself. This is the first reported case of an acquired dural arteriovenous malformation of the anterior cranial fossa verified by angiography. This rare lesion is discussed with regard to its etiology.
