Massive epistaxis secondary to pseudoaneurysm of internal carotid artery.

Post-traumatic pseudoaneurysms of internal carotid arteries are uncommon. The patients may present with massive epistaxis due to rupture of the aneurysm into the sphenoid sinus. Early diagnosis and treatment is mandatory as the likelihood of exsanguinations increases with each subsequent episode of epistaxis. The clinical features of unilateral blindness and massive epistaxis after head injury should indicate the diagnosis. The high mortality of this entity underlines the importance of early angiography in these patients to confirm this diagnosis. We present 3 cases of post-traumatic aneurysm of the ICA.
