Bilateral Carotid-Cavernous Fistula Following Traumatic Fall: A Case Report

Abstract

Carotid-cavernous fistulas (CCFs) are abnormal connections between the carotid arteries and the cavernous sinus, posing significant neuro-ophthalmologic risks. This report presents a rare case of bilateral post-traumatic CCFs, focusing on clinical presentation, diagnosis, and management. Symptoms mimic conjunctivitis, causing diplopia, exophthalmos, and ophthalmoplegia. Diagnosis relied on computed tomography, magnetic resonance angiography, and digital subtraction angiography. Management involved transarterial embolization with coils, achieving successful outcomes. This highlights the importance of timely intervention and comprehensive imaging to prevent complications. Teaching point: This case report details a rare instance of bilateral post-traumatic carotid-cavernous fistulas, emphasizing clinical presentation, diagnostic evaluation, and management.
