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.
树突状肺骨化是一种罕见的疾病，其特征是分支状骨刺。一名 33 岁的男子临床被认为患有结节病。53 岁时，另一位主治医生进行了详细评估。计算机断层扫描（CT）显示细结节模式，有钙化灶，肺功能检查显示周围气道阻塞。我们进行了手术活检。组织学检查显示树突状肺骨化。手术后，CT 显示一些病变进展；肺功能也略有下降。由于树突状肺骨化可能是一种进行性疾病，我们应该进行长期随访。
