Disseminated coccidioidomycosis associated with hypercalcemia

This article describes a patient in whom disseminated infection with coccidioidomycosis was associated with hypercalcemia. The patient had a low level of 1,25-dihydroxyvitamin D and a suppressed parathyroid hormone value, an indication that the hypercalcemia was not mediated by vitamin D or parathyroid hormone. The episode resolved readily with administration of pamidronate, an outcome suggesting that this is effective treatment of hypercalcemia of this origin. On follow-up of the patient while he was receiving antifungal therapy for Coccidioides immitis, calcium values remained normal.
