Background:
Carotid cavernous fistula is a rare complication that is typically associated with head trauma and skull base fractures. The traumatic bilateral carotid cavernous fistula are significantly rarer.
Case Presentations:
We report a case of a 61-year-old man presenting with unilateral exophthalmos, swollen eyelids, conjunctival congestion, and edema etiologically associated with severe trauma. Thereafter, the patient demonstrated symptoms of contralateral oculomotor nerve injury caused by skull base fracture, such as ptosis of eyelid, dilated pupils, and eye movement disorder, and was diagnosed with bilateral carotid cavernous fistula.
Conclusions:
The patient recovered after undergoing endovascular embolization of bilateral cavernous sinus fistulas. The patient demonstrated the classic symptoms of an extremely rare condition known as bilateral carotid cavernous fistula, in only one eye. Reporting and analyzing this case will help us elucidate the underlying mechanisms of this disease.
