title: [Metastatic pulmonary calcification: a rare cause of interstitial lung disease].
abstract: We report the case of a 58-year-old woman with metastatic pulmonary calcinosis who presented with bronchial hyperreactivity. She was receiving calcium and vitamin D supplementation following total bilateral thyroidectomy with parathyroidectomy and had a history of episodes of symptomatic hypercalcemia secondary to exogenous administration. Lung function testing showed slight obstruction that was reversed by bronchodilators. Images showed a bilateral micronodular pattern mainly in the upper fields (x-ray and high resolution computed tomography of the thorax) and abnormal calcium deposition in the lungs (bone scintigraphy). The diagnosis was established by transbronchial biopsy. The clinical course was favorable. Metastatic pulmonary calcinosis is rare and usually asymptomatic and evolution is good. This entity should be taken into account in the differential diagnosis of interstitial lung diseases involving micronodular infiltrates in patients at risk.
