title: [Severe acute hypercalcemia in a child caused by accidental vitamin D poisoning].
abstract: The authors report a case of acute severe hypercalcemia (5.20 mmol/l) in a 9-month-old boy. Vitamin D poisoning is confirmed by high serum level of 25 OHD (287 mcg/l; N = 10-60) while the source of intoxication is unknown. Individual idiopathic vitamin D hypersensitivity is eliminated because of a negative diagnosis test. Management with prednisone, high intravenous fluid saline intake, furosemide and calcitonin results in a favourable outcome. Vitamin D intoxication has always to be evoked when acute severe hypercalcemia occurs in infants.
