High resolution computed tomographic features of pulmonary alveolar microlithiasis

We conclude that patients with PAM may have all findings of interstitial lung disease in varying degrees as well as MNs on their HRCTs. More importantly, this study suggests a proportional relationship between profusion of MNs and parenchymal alterations in patients with PAM. This study also suggests that the degree of parenchymal alterations closely related with the degree of pulmonary function loss in patients with PAM.
