CTICasesDendriform Pulmonary Ossification
Imaging findings
Chest radiograph shows coarse, dense reticular opacities throughout the lungs. Bone-window CT demonstrates widespread, branching bone formation (dendriform calcification/ossification) within the lung interstitium. The intervening lung parenchyma is normal.
Key takeaways
Dendriform pulmonary ossification is a rare, slowly progressive condition where mature bone tissue forms within the alveolar septa. It is typically idiopathic, benign, and does not cause significant pulmonary impairment.
