Coexistence of DiGeorge syndrome with Fahr syndrome, mosaic Turner syndrome and psychiatric symptoms - a case report.

We report a case of a 63-year-old patient with psychiatric symptoms diagnosed with coexisting DiGeorge syndrome, Fahr syndrome and Turner syndrome. To our knowledge, this is the first reported case of coexistence of DiGeorge syndrome and mosaic Turner syndrome. Basal ganglia calcification, known as Fahr syndrome, may develop in patients with DiGeorge syndrome as a consequence of calcium-phosphate balance disturbances resulting from primary hypoparathyroidism.
