A carotid-cavernous fistula is a rare abnormal communication between carotid vasculature and the cavernous sinus. Development of a carotid-cavernous fistula often results from trauma, but may be spontaneous in the setting of predisposing risk factors. Suspicion for a spontaneous fistula is understandably low on routine non-contrast imaging. In this article, we present a case of a carotid-cavernous fistula initially presenting with the potentially underrecognized imaging manifestation of diffuse pituitary enlargement identified on a non-contrast CT, later revealed to be due to the presence of the fistula.

We report a rare case of a missed intracavernous internal carotid artery dissecting aneurysm occurring as a complication of the base of skull fracture with severe brain injury causing acute cavernous sinus syndrome with permanent vision loss. A 31-year-old Myanmar lady had an alleged motor vehicle accident and suffered severe traumatic brain injury with multiple intracranial bleeds, multiple facial bone and base of skull fractures, and limb fractures. At one week post-trauma, she had severe right eye proptosis with vision loss, ophthalmoplegia, chemosis, and high intraocular pressure.

Traumatic direct type carotid cavernous fistula (CCF) is an acquired arteriovenous shunt between the carotid artery and the cavernous sinus post severe craniofacial trauma or iatrogenic injury. We reported a 46-year-old woman who had developed a traumatic direct type CCF after severe head trauma with a skull base fracture and brain contusion hemorrhage. The clinical manifestations of the patient included pulsatile exophthalmos, proptosis, bruits, chemosis, and a decline in consciousness.

A carotid cavernous fistula (CCF) is a disruption in the carotid arteries within the cavernous sinus. The pooling of blood in the sinus causes a myriad of neurological deficits. When correctly diagnosed, this condition can be easily managed through surgical intervention.

Carotid-cavernous aneurysms (CCAs) have the potential for growth, and their risk of rupture can lead to severe complications. Treatment is typically recommended to prevent these complications, with endovascular therapy being the preferred approach due to the challenging surgical access. This case presents a rare instance of rupture of a CCA that had been previously treated with a flow-diverting stent, which resulted in the development of a carotid-cavernous fistula, requiring venous access endovascular treatment.

The treatment of indirect carotid-cavernous fistula (CCF) poses a unique challenge. Currently, endovascular interventions remain the principal treatment option with high cure rates and acceptable safety profiles. The anatomical characteristics of individual cases determine the optimal vascular access routes (transvenous vs.
