Résumé
The enlargement of giant intracranial aneurysms (IA) can be observed in 30 % of cases resulting in a neurological deficit and epilepsy due to its mass effect. This growth process could be due to a morphological disorder of the IA wall. The authors report on 2 cases of giant IA growth responsible for intracranial hypertension. The treatment of these giant IA required a microsurgical excision combined with a series of cerebral revascularization procedures. The role of vasa vasorum on the inflammatory granuloma outside the vessel, which induced the enlargement, is discussed. These cases illustrate the abluminal vasculopathy as the main involvement of this unfavourable natural history.
