title: [Concurrence of Fahr's disease with cerebellar tumors].
abstract: Fara's disease or idiopathic calcification of the basal ganglia is a rare disease that is characterized by multiple petrificates in the area of the basal ganglia, caudate nucleus, and dentate nuclei of the cerebellum. As of now, only two cases of a concurrence of Fara's disease and brain tumors have been described. The authors present two more cases. Both cases are unique since the tumors occurred in the presence of Fara's disease symmetrically, as in the mirror, in the cerebellar hemispheres at the periphery of petrificates. This may be confirmed by the fact that astrocytic proliferation and hyperplasia around the calcified vessels are a cause of neoplasms.
