[Fahr syndrome secondary to primary hypoparathyroidism: about a case].

Fahr syndrome is a rare anatomo-clinic disease whose most common cause is primary or postoperative hypoparathyroidism. It is characterized by bilateral and symmetrical intracerebral calcifications located in the central gray nuclei, most often associated with phosphocalcium metabolism disorders. We here report the case of a 54-year old patient who had been treated for primary hypoparathyroidism for 20 years, presenting with amnesic disorders revealing Fahr syndrome secondary to hypoparathyroidism.
