Abstract/OtherAbstract:
BACKGROUND: A posttraumatic carotid cavernous fistula can remain unrecognized and ultimately present with symptoms characteristic for a middle cerebral artery stroke. Progressive neurologic deterioration can occur until the condition is diagnosed and treated. If unrecognized and untreated, permanent damage may result.
CASE REPORT: A 46-year-old white man with the history of a motor vehicle crash 6 months prior presented with complaints of acute onset of expressive aphasia and seizure-like activity for 3 days. On presentation, the patient was noted to have moderate proptosis and chemosis of the left eye. Magnetic resonance imaging of the brain showed an arteriovenous fistula arising from the anterolateral precavernous left internal carotid artery. This was directly communicating with the adjacent cortical veins along the medial aspect of the left temporal lobe, resulting in venous congestion in the left frontal opercular region, the left insula, and subinsular tracks. The patient underwent an intracranial coil embolization of a left carotid cavernous fistula. No complications were encountered, and the patient had near-complete resolution of neurologic deficits and left eye proptosis. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Although posttraumatic carotid cavernous fistula is a rare condition, it is important to be aware of this entity because immediate diagnosis and treatment may improve outcome.
