Calcium deposits may induce a lung reaction with alveolar organizing exudates evolving to fibrosis. The computed tomography (CT), and especially high-resolution CT (HRCT), when compared with plain films has higher sensitivity to detect mild differences in lung density, morphology, and distribution of the lesions, and associated abnormalities. Like lung consolidation, it looks like white areas against the darker air-filled lungs on your chest X-ray. The condition is marked by induration (swelling or hardening of normally soft tissue) of a normally aerated lung. Intra-alveolar accumulation of spherical microliths is seen at histopathology.
