[A case of anterior condylar confluence dural arteriovenous fistula with initial onset of ocular symptoms].

To report a case of anterior condylar confluence dural arteriovenous fistula (ACC dAVF) with initial onset of ocular symptoms. A 63-year-old man with conjunctival injection and eyelid edema with a suspected carotid cavernous fistula (CCF) was referred to our department by the department of neurosurgery of our hospital. On his first visit, his left eye showed marked conjunctival injection and eyelid edema OS. Those findings were consistent with CCF, however, three-dimensional angiography indicated a diagnosis of ACC dAVF. His ocular symptoms improved immediately following transvenous embolization with coils at the shunting point. Although most cases of ACC dAVF start with tinnitus, this case showed ocular abnormalities without tinnitus as the initial symptoms.
