Immobilization-induced hypercalcemia (IIH) is a rarely seen condition of which etiology is unclear. It has been described as a complication in adult patients with prolonged movement limitations depending on severe acute trauma, multiple bone fractures, and stroke or young adults with immobilization depending on spinal cord injuries. Diagnosis requires a detailed evaluation to exclude other conditions causing hypercalcemia. This is a case report of a 64-year-old male with prolonged immobilization related to hypoxic brain injury who presented with severe hypercalcemia and contributed to identifying hypercalcemia as a result of immobilization.
