CTICasesDendriform Pulmonary Ossification
Imaging findings
Lip-slab CT format demonstrates stable, branching, subpleural branching calcifications in the lower lung zones over eight years. Biopsy confirmed mature lamellar bone with osteocytes, fat, and marrow spaces, representing dendriform pulmonary ossification.
Key takeaways
Dendriform pulmonary ossification is a rare form of pulmonary calcification where mature lamellar bone forms in the lung parenchyma. It typically presents as stable, branching, subpleural calcified lines in the lower lobes and is often associated with chronic lung injury.
