Traumatic pseudoaneurysm of the intracavernous internal carotid artery(ICA) is extremely rare, but it is life threatening condition because of massive recurrent epistaxis. Unfortunately, the prompt diagnosis and treatment of this disease are frequently delayed due to its rarity and variable latent period, so this disease is regarded as a challenge to clinicians. Optimal therapy for this diseases demands rapid suspicion for it and is essential in order to give the best functional outcome with minimizing its morbidity and mortality. The authors present a case of male patient with traumatic pseudoaneurysm of intracavernous ICA accompanying severe epistaxis. This patient was a 37-year-old male with unilateral blindness and recurrent massive epistaxis after suffering trauma to head. Computed tomography, MRI and carotid artery angiogram showed pseudoaneurysm of intracavernous ICA with sphenoid bone fracture. The patient was effectively managed with occlusion of the pseudoaneurysmal circulation by endovascular interventional embolization technique utilizing mechanically detachable tungsten coils.
