Dendriform Pulmonary Ossification: Findings from Eight Years of Observation

Dendriform pulmonary ossification is a rare condition characterized by branching bony spicules. A 33-year-old man was clinically considered to have sarcoidosis. At 53 years old, another attending physician performed a detailed evaluation. Computed tomography (CT) showed a fine nodular pattern with f...

Description
Summary:Dendriform pulmonary ossification is a rare condition characterized by branching bony spicules. A 33-year-old man was clinically considered to have sarcoidosis. At 53 years old, another attending physician performed a detailed evaluation. Computed tomography (CT) showed a fine nodular pattern with foci of calcifications and pulmonary function testing showed peripheral airway obstruction. We performed a surgical biopsy. A histological examination revealed dendriform pulmonary ossification. After surgery, CT showed progression of some lesions; the pulmonary function had also decreased slightly. Since dendriform pulmonary ossification might be a progressive disease, we should perform long-term follow-up.
