A 4-year-old boy was found to have rickets associated with normal serum levels of 25-hydroxyvitamin D and high serum levels of 1,25-dihydroxyvitamin D. These findings were thought to be the result of dietary calcium deficiency caused by the prolonged elimination from his diet of cow milk and milk products because of allergy. Adequate intake of calcium resulted in rapid improvement.
