A case of communicating carotid-cavernous sinus fistula (CCF) after minor closed head injury is presented. A 45-year-old Caucasian male presented to the emergency department of a tertiary care hospital with the chief complaint of blurred vision and facial numbness.

CT and MRI confirmed the suspicion of carotid-cavernous sinus fistula, which was managed by cerebral angiography with coil embolization of this fistula. The patient was symptom free at the 8-month follow-up. Carotid-cavernous sinus fistula is a rare condition that is usually caused by blunt or penetrating trauma to the head, but can develop spontaneously in about one fourth of patients with CCF. The connection between the carotid artery and cavernous sinus leads to increased pressure in the cavernous sinus and compression of its contents, and thereby produces the clinical symptoms and signs seen.
