title: Pulmonary alveolar microlithiasis: a report on four cases.
abstract: The accidental discovery of a diffuse but sharply defined micro-nodular pattern on routine chest x-ray of an asymptomatic patient makes the diagnosis of pulmonary alveolar microlithiasis more likely whereas the finding of different sized microliths that are located in alveolar spaces, in a lung biopsy specimen, confirm the diagnosis. Four cases are reported in this context.
