title: Hypercalcemic encephalopathy in the course of hyperthyroidism.
abstract: A hypercalcemic condition can be observed in association with hyperthyroidism. The case of a patient suffering from hypercalcemia and hyperthyroidism is reported. A confusional state and EEG alterations, among which diffuse monomorphic delta rhythms were remarkable, are shown. As soon as normalization of calcemia was achieved, a rapid clinical and EEG improvement took place. A hypothetical interpretation is proposed, according to which a prolonged, though inconstant, and mild hypercalcemia in the course of hyperthyroidism could determine an encephalopathy, concealing in some way thyrotoxic symptoms.
