CTICasesDendriform Ossification
Imaging findings
CT demonstrated bilateral tiny, punctate, calcified nodules, particularly in the lower lobes. Pathology confirmed intra-alveolar dystrophic ossification, which also featured components of organizing pneumonia.
Key takeaways
Dendriform ossification can appear as diffuse pulmonary calcifications and should be considered in the differential of diffuse nodular lung disease. It can be associated with organizing pneumonia and fibrosis.
