Posttraumatic carotid cavernous fistula that presented as seizure and focal neurological deficits with symptom resolution after therapeutic coil embolization.

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.
