[Familial form of Fahr syndrome (report of two cases)]

Two cases of familial form (in brothers) of extensive, symmetric, idiopathic calcifications of the basal ganglia and cerebellum (Fahr syndrome) are described. In discussion of factors predisposing to appearance of such idiopathic calcifications, particular attention was given to meningoencephalitis suffered in childhood and coexistence of a tumour of the sella of prolactinoma type, in case 1. Attention was also called to progressive, copious clinical and radiological symptology of the discussed cases. It was impossible to suggest a probable type of inheritance (parents of the patients were dead).
