A case of double ophthalmic arteries arising from the internal carotid artery with unique features is reported. This case was discovered following in the course of time the progress of a thrombosis of the anterior cavernous sinus associated with a low-flow direct arteriovenous fistula of the superior ophthalmic vein. At different time points, the same patient underwent four angiographic studies and one computerized tomography with contrast medium. Angiographies showed that the double internal carotid artery origin of the ophthalmic artery was detectable only within a short range of time. To the best of our knowledge, this case is unique as it demonstrates that a second ophthalmic artery may lie hidden, showing itself only under particular hemodynamic requirements.
