Carotid cavernous fistulas (CCF) are a rare complication which involves abnormal communication between the internal or external carotid artery and the cavernous sinus. Trauma is the most common etiology. This paper discusses a case of unusual presentation of CCF treated by embolization. A 35-year-old male patient was involved in a motorcycle accident with facial trauma and sought evaluation four days after trauma with amaurosis and clinical signs of CCF, that was confirmed by angiography. The patient was subjected to embolization after which he reported feeling better; however, ten days after embolization, chemosis increased. The condition was followed-up and there was no need for reintervention, since the condition remained stable and presented clinical improvement on the 15th day after embolization. At present, patient’s condition is stable, without chemosis, with vision loss on the left side, without neurological deficit, improvement in eyeball movement, and with palpebral ptosis on the left side. This paper reinforces the importance of correct clinical examination in patients subjected to trauma, paying attention to signs and symptoms of CCF and to multidisciplinary treatment, so as to minimize the consequences of CCF.
