A 61-year-old woman complained of dizziness after a fall. Her medical history was remarkable for an operation for bilateral cataract at the age of 29 years and an episode of tetany at the age of 47 years, which led to the diagnosis of primary hypoparathyroidism. Since then, she had been treated with calcium supplements and vitamin D with relatively regular laboratory evaluation and reported no symptoms. There was no family history of neurological disease or hypoparathyroidism.
