[Morphology of the Fahr syndrome (idiopathic calcification of the cerebral vessels)].

Two observations of the Far syndrome manifested by calcification of the brain tissue, oligodendroglia, arterial walls, arterioles, capillaries and veins are described. In the first case, the Far syndrome developed against the background of hypoparathyreosis with longterm disturbance of phosphorus-calcium metabolism, in the second--against the background of endocrine polyadenomatosis (trabecular adenoma of the thyroid gland, clear cell adenoma of the adrenals) with hyponatremia.
