Abstract :
The authors reported a patient with unilateral blindness of the left eye after trauma. Apart from
paralysis of the 4th cranial nerve and mild optic nerve edema, there was no structural problem
during the ophthalmologic examination. Brain CT scan, CT angiography and MRI demonstrated
aneurysm in the left pericavernous region. The patient underwent angiography for coiling of
the aneurysm, which detected large carotid cavernous fistula (CCF) mainly draining into the
petrous sinus. Therapeutic embolization was performed with balloon and the CCF vanished
completely. The most important points of this case are the blindness without exophthalmia as
the only presentation of CCF which has not been reported as the only symptom and failure of
CT-angiography and MRI evaluation for the diagnosis of CCF.
