ABSTRACT
CASE PRESENTATION A 51-year-old man presented with a 6-month history of progressive rigidity, slowness, and cognitive difficulties. At the age of 5, he had developed cramping in his legs, difficulty walking, tetany, and convulsions, and was diagnosed with primary (idiopathic) hypoparathyroidism. Despite treatment, he developed renal calcifications by age 13. His condition remained stable for many years with only one hospital admission 4 years ago due to a medication change leading to hypocalcemia. He maintained an active family, social, and professional life with no limitations.
