Hungry bone syndrome secondary to prostate cancer successfully treated with radium therapy

A 50-year-old man with a history of prostate cancer with extensive bone metastasis and hypocalcaemia presented with muscle aches and cramps. Physical exam was significant for Chvostek's and Trousseau's sign. Laboratory assessment was consistent with profound hypocalcaemia. This was believed to be due to hungry bone syndrome secondary to advanced prostate cancer. He was treated with intravenous calcium, vitamin D and calcitriol. He also received three doses of radium²²³ therapy. After therapy, hypocalcaemic episodes resolved. Follow-up after 2.5 years showed continued resolution of hypocalcaemia.
