Familial incidence of cerebral aneurysms.

a patient with middle cerebral aneurysm whose twin brother might have died from a cerebrovascular accident eight years previously. Jokl and Wolffe (1954) described sudden death from such diseases in identical twins. Chambers et al. (1954) were the first to detect this malady in father and son. Ross (1959) noted the occurrence of cerebral aneurysms in mother and daughter. Ulirich and Sugar (1960) reported the disorder in members of the same family--in two pairs of brothers, one uncle-nephew pair, and one brother-sister pair. In the European countries there have been occasional references on the subject in the German literature (Eck, 1957; Krayenbiihl and Yasargil, 1958), but none in the English literature. In a survey of 337 cases of proved intracranial aneurysms admitted to our unit during the period 1957 to 1965 six cases showed this familial incidence.
