[Abducent nerve palsy as the only symptom of intracavernous carotid aneurysm in a child].

A case of a 10-year old child with isolated sixth nerve palsy due to giant intracavernous carotid aneurysm is presented. The aneurysm was confirmed by CT brain scan and carotid angiography. It was closed after local embolization of internal carotid artery with the use of platinum inlays. It turns out that an intracranial aneurysm can be, although very rarely, the cause of isolated sixth nerve palsy in childhood.
