Internal carotid artery (ICA) aneurysms are an unusual but serious cause of epistaxis. This epistaxis is massive and sometimes uncontrollable threatening the vital prognosis of patients. We report the case of a 16-year-old adolescent received in emergency with severe bilateral epistaxis, asthenia and grade-3 left exophthalmos. In his history, the subject had been the victim of an assault six months before consultation. He had received blows on the cephalic extremity with light but repeated epistaxis. The treatment consisted to blood products transfusion and local compression by sterile gazes. An ICA aneurysm in sphenoid sinus has been confirmed in a craniofacial CT scan coupled to vascular opacification. Although the ICA has a variable course in contact with the sphenoid sinus, massive epistaxis would be the consequence of a pronounced dehiscence of the ICA in the sphenoid sinus, particularly in a traumatic context. In front of this type of epistaxis in our context, general practitioners must be able to suspect a ruptured ICA aneurysm in the presence of exophthalmos and a notion of old or recent cranio-encephalic injury. Additionally, due to the high morbidity and mortality of this condition, a monitoring algorithm is necessary for patients with head trauma to facilitate early detection.
