Giant cerebral aneurysms account for approximately 5% of all intracranial aneurysms, affecting morecommonly women in the 5th to 7th decade. When untreated, giant intracranial aneurysms face a poor prognosis withan estimated 2-year mortality of 68%. We present the case of an 82-year-old woman admitted at the emergencydepartment due to two focal to bilateral tonic-clonic seizures with a giant aneurysm of the supraclinoid segment ofthe right internal carotid artery on the CT scan. We discuss different management approaches for giant internalcarotid artery aneurysms, including direct surgical clipping, reconstructive endovascular procedures (coiling, balloon-/stent-assisted coiling, and flow diversion), deconstructive endovascular techniques (parent artery occlusion), andconservative management.
