[Familial cerebral aneurysms: case report and review of the literature].

Familial occurrence of cerebral aneurysms is rare. About 80 families affected by these lesions have been reported in the international literature to date. The authors describe three members of a family presenting intracranial aneurysms without other congenital associated anomalies. Clinico-pathological features, with regard to the possibility of an early and a more effective diagnostic and therapeutic approach, are presented and discussed in the light of the available literature on this topic.
