Alternatively, but less likely, some patients with hypoparathyroidism are discovered not so much from symptoms, but by the discovery of hypocalcemia from a biochemical screening test. Ectopic calcification can also occur in the context of chronic hyperphosphatemia, even if the calcium-phosphate product is not exceeded.
