Abstract

ALTHOUGH elevation of the serum calcium level is associated with a variety of conditions, the most pronounced alterations occur in hyperparathyroidism. This disease process is characterized by anorexia, nausea, vomiting, thirst, and polyuria, with associated muscular weakness, confusion, and drowsiness which may progress to lethargy and coma. The symptoms are attributed directly to "calcium intoxication," and the syndrome constitutes medical and surgical emergency since it represents the only potentially lethal hypercalcemic state than can be cured.1 This report describes a case in which the correct clinical diagnosis was clouded by the occurrence of convulsions with hypercalcemic coma. Since seizures have never been included in the symptom complex of hyperparathyroidism, this paper reports a case in which hypercalcemia indirectly resulted in central nervous system hyperactivity and relates these symptoms to the underlying disease.
