[Pulmonary calcification in vitamin D poisoning in an infant].

We describe the case of a child aged 11 months with vitamin D intoxication and hypercalcemia, who developed acute renal failure and dyspnea. Chest X-rays showed interstitial changes compatible with either pulmonary alveolar proteinosis or pulmonary edema. The hypercalcemia suggested the possibility of metastatic calcifications of the lung. This hypothesis was subsequently confirmed by the progressive disappearance of pulmonary findings as calcemic levels returned to normal values... Our report emphasize the opportunity of studying the respiratory system in each patient with hypercalcemia, whichever the etiology may be.
