A 70-year-old woman with hyperparathyroidism associated with parkinsonism is reported. Her primary initial symptom was parkinsonism, but it was levodopa-resistant. Chemical and hormonal findings revealed that she had hyperparathyroidism. The symptoms were relieved after the surgical removal of a parathyroid adenoma. Although this type of case has been reported only rarely, it suggests that hypercalcemia might be an aggravating factor in levodopa-resistant parkinsonism.
