ABSTRACT
Introduction The incidence of intracranial aneurysms in the pediatric population is low, and endovascular treatment is becoming a safe and minimally invasive treatment option. In the present study, the occurrence of special features of cerebral aneurysm in children, in comparison to adults, is also described. Case Report A 3-month-old female infant presented with progressive proptosis and divergent strabismus at the right eye, in addition to inconsolable crying. Cerebral resonance, angiotomography and angiography exams demonstrated angiodysplasia in the right internal carotid artery with two large paraclinoid dissecting aneurysms with wide neck. The right internal carotid artery was occluded with coils by endovascular approach, without detriment to the perfusion of the ipsilateral hemisphere and without neurological deficits. The patient achieved good recovery, and a late control angiotomography confirmed the exclusion of the aneurysms. Conclusion Parent artery sacrifice via endovascular approach is an effective therapeutic option, but a long-termfollow-up is necessary to avoid recurrence and bleeding.
