Computed tomography of pulmonary fibrosis and dendriform pulmonary ossification

Axial chest computed tomography (CT) scan from patient with dendriform pulmonary ossification. Lung window (A) demonstrates innumerable 2 to 5 mm calcific densities distributed in a branching pattern, predominantly in a peripheral and subpleural distribution. Bone window (B) of the same image identifies the calcification of the branching lesions.
