A Case of Pulmonary Alveolar Microlithiasis / 결핵및호흡기질환

ABSTRACT

Pulmonary alveolar microlithiasis is a rare disease of unknown etiology that is characterized by the presence of calcific concentrations in the alveolar spaces. The radiographic appearance is pathognomonic. Plain chest radiographs show a white lung or sandstorm lung consisting of fine sand like microcalcifications diffusely scattered throughout both lungs with a higher density at the lung bases. We now report the case of a 67-year-old male whose diagnosis was based on characteristic findings on a chest X-ray and a high-resolution computed tomography scan.
