[Diffuse intracranial arterectasias: megadolichocarotids, megadolichovertebrals].

Intracranial diffuse arteriectasis may be located to the carotid and vertebral arteries and their branches separately or concomitantly and associated with saccular aneurysms and generalized arteriectasis. The principle clinical aspects of intracranial arteriectasis are cranial nerve palsies, particularly of the cerebellopontine region in association or not with cerebellar disorders and transient or permanent motor deficiencies.

[Tumoral forms of tuberous sclerosis. The clinical and therapeutic importance of concomitant hydrocephalus (author's transl)].

In a young man and a pregnant young woman presenting since childhood of tuberous sclerosis without epilepsy or mental disorders severe intracranial hypertension developped secondary to obstructive hydrocephalus. Ventriculo-peritoneal shunting unilateral in the first case, bilateral in the second, releaved the patients of all their symptoms.
