Spontaneous obliteration of a carotid-cavernous fistula associated with fibromuscular dysplasia of the internal carotid artery.

The authors present a case of spontaneous recovery of a carotid-cavernous fistula associated with fibromuscular dysplasia of the aortocranial vessels in a 31-year-old woman. The pathogenesis of the carotid-cavernous fistula and the possible mechanism responsible for its spontaneous obliteration are both discussed.
