We present five cases with confirmed diagnosis of pulmonary alveolar
microlithiasis that illustrate the appearance of
this rare chronic lung disease on conventional and high-resolution
CT. Pulmonary alveolar microlithiasis is
characterized by widespread intraalveolar calcification of both lungs.
Conventional CT confirmed the inferior and
posterior predominance of the lesions in four of our cases and showed
an exceptionally high concentration of microliths
in the subpleural parenchyma and along the bronchovascular bundles.
High-resolution CT revealed a perilobular and
bronchovascular distribution of the disease process at the level of
the secondary pulmonary lobule. This pattern
correlated closely with pathologic findings.
