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.展开更多

The exact cause is unclear: they may be congenital or result from trauma, infection, or radiation. Aim: We report a case of massive otorrhagia and epistaxis from a ruptured aneurysm of the petrous internal carotid artery. Case Presentation: A 34-year-old man presented to our department for the first time with repeated left otorrhagia ongoing for 5 years, left sided pulsatile tinnitus and left conductive hearing loss. In his history, we noted a right hemi-corporeal deficit of sudden onset one month ago and the head-CT showed a left frontoparietal subarachnoid hemorrhage without any visualised vascular malformation. Otomicroscopy showed a pulsatile mass visible at the posterior part of the hypotympanum. There was a right-sided hemiparesis estimated at 2/5 with no disorder of the sensitivity. After hemodynamic stabilization, the patient was discharged from the hospital and treatment was scheduled in interventional radiology and neurosurgery unit. Unfortunately the patient presented at home with a cataclysmic hemorrhage by massive otorrhagia and epistaxis and arrived dead at the emergency unit. Conclusion: The treatment of a petrous carotid aneurysm must be carried out quickly considering the risk of rupture leading to a cataclysmic hemorrhage that can be rapidly life threatening.展开更多

The lack of frank pulsatility and signs of inflammation though was a bit confusing, the Doppler and CT angiogram clinched the diagnosis. We were able to surgically resect and reform the ICA using the native vessel itself, which is an unusual technique, which we thought was worth presenting.展开更多

Many variations in its origin and course have been observed;however, as far as we know, the association of true aneurysm of the PMA and its anomalous origin from the internal carotid artery has not been reported previously. We reported the case of a 59-year-old woman who suddenly presented a loss of consciousness without head trauma, computed tomography (CT) revelated intracerebellous hematoma associated with a subarachnoid hemorrhage of the posterior cerebral fossa. Cerebral angiography demonstrated a true aneurysm of the PMA which originated from the internal carotid artery.展开更多

One of the causes of vocal cord paralysis is the disruption of vagus nerve innervation to the vocal cords by the mass effect of a neighbouring structure. We report a rare case of vocal cord paralysis secondary to internal carotid artery dissection. Method: The diagnosis was based on clinical history, physical examination and imaging studies. Literature review was done. Case Report: This was a 53-year-old female with a history of unremitting, progressive hoarseness and mild dysphagia to liquid, who was clinically found to have impaired left vocal cord mobility, a left-sided pulsatile neck mass and left carotid artery dissection based on imaging studies. Symptoms abated after conservative treatment with Aspirin and she has remained symptom free since two years of follow-up. Conclusion: Vocal cord paralysis can be a consequence of carotid artery dissection causing mass effect on the vagus nerve. Thus, carotid artery dissection should not be forgotten as a possible cause of vocal cord paralysis in some cases of vocal cord paralysis of uncertain etiology. Treatment with anti-platelet drug can bring about resolution of symptoms and return of vocal cord mobility.展开更多
