A Case of Carotid Cavernous Fistula Presenting with “Delayed Red-Eyed Shunts”: Ki Bum Sung, Won Hee Chung, Jeong Ho Park, Dae Ho Kim; J Korean Bal Soc. 2006;5(2):307-310.

Abstract PDF: Presenting symptoms of carotid cavernous fistulas (CCF) may vary according to the draining vessels. Prominent external orbito-ocular signs such as red eye, proptosis, ocular bruit occur, when the shunt drains anteriorly (“red-eyed shunts”), whereas an isolated ocular motor nerve palsy and headache can be the only presenting symptoms when it drains posteriorly (“white-eyed shunts”). Turning the eyes red from white eyed-shunt weeks to months (“delayed red-eyed shunts”) suggest the direction of fistula drainage shifted anteriorly; it has rarely been reported. We report a patient with delayed red-eyed shunts whose red eye resolved after chemical embolization of draining vessels. Key Words : Carotid cavernous sinus fistula, Ocular motor nerve palsy

Specific MRI and MRA findings of Dural Carotid Cavernous Sinus Fistula -A Case Report-: Won Hee Chung, Jong Se Lee, Tae Kyeong Lee, Ki Bum Sung; J Korean Bal Soc. 2006;5(2):296-298.

Abstract PDF: Dural carotid-cavernous sinus fistula (d-CCF) is a rare cause of ophthalmoplegia, and it may be overlooked when the prominent external orbito-ocular sign is lacking. Conventional angiography is the gold standard in the diagnosis of d-CCF. Recently, the specific MR findings of d-CCF have increasingly been reported. We report a patient with spontaneous d-CCF presenting with an isolated fourth-nerve palsy in whom magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) demonstrated d-CCF. Key Words : Carotid cavernous sinus fistula, Ophthalmoplegia, Angiography, Magnetic resonance imaging, Magnetic resonance angiography
