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.
报告了1例双额开颅术后发生的前颅窝硬脑膜动静脉畸形病例。病灶主要由左侧筛前动脉供血，经右侧外侧裂静脉及眼上静脉引流，上矢状窦通畅。病灶本身导致左侧额叶出血。这是首例经血管造影证实的后天性前颅窝硬脑膜动静脉畸形病例。对这一罕见病变的病因进行了讨论。
