Abstract
|
|
|
|
Isolated trochlear nerve palsy due to dural carotid-cavernous fistula (CCF) is extremely rare. We report a case of trochlear nerve palsy caused by a dural CCF, which was successfully treated by transvenous embolization. A 62-year-old man presented with vertical diplopia. On neurologic examination, we discovered a trochlear nerve palsy on his left eye, but did not detect any abnormalities in other tests including brain imaging. Over the year, the patient’s symptoms continued to worsen. Eventually, an orbital CT with angiography revealed a dural CCF involving his left side.
