摘要
Dural arteriovenouscommunications betweenfistulas （DAVFs） are directthe intracranial arterial andvenous systems without an intervening nidus. Clini-cians sometimes fail to give a correct diagnosis ofDAVF. Given the similarity of their clinical andmagnetic resonance imaging （MRI） manifestations,diagnostic confusion may arise between DAVF andcerebral venous sinus thrombosis （CVST） （Simonet al., 2009）.
