An uncommon cause of epistaxis: cartoid cavernous fistula.

We report on an uncommon cause of epistaxis presenting to the emergency room. Epistaxis is not an uncommon presentation to emergency rooms across the world. The majority are easily controlled and have low mortality. We present a case of a carotid-cavernous fistula presenting with massive epistaxis culmination in cardiovascular collapse and death. Awareness of this entity will reduce the frequency of this condition resulting in major morbidity and mortality.
