[Alveolar microlithiasis. Non-invasive diagnosis using alveolar lavage and technetium scintigraphy].

A new case report of alveolar micro-lithiasis shows the diagnostic interest of two non invasive explorations to affirm a radiologic suspicion. Technetium showed calcium in the lung. The broncho-alveolar lavage, realised with a big quantity of fluid, removed the microliths. These two technics together avoid pulmonary biopsy.
