Intracerebral bilateral symmetrical calcifications, demonstrated in a patient with pseudohypoparathyroidism

Bilateral Symmetrical Calcifications (B.S.C.) in cerebro represent calcium deposits usually found in the basal ganglia and/or dentate nucleus. They can be the result of diverse disorders, but can also present themselves without any underlying disease. Most often they are asymptomatic, but if the calcifications are extensive, extrapyramidal and cerebellar signs may arise. The following case concerns a patient with pseudohypoparathyroidism. Besides the usual signs and symptoms found in this disease, the patient also showed extensive B.S.C. The etiology and clinical symptoms of B.S.C. will be discussed. Furthermore, attention will be given to the syndrome of the pseudohypoparathyroidism and the effects of hypocalcemia.
