Dendriform pulmonary ossification complicated by recurrent spontaneous pneumothorax: Two case reports and a review of the literature.

ABSTRACT:

Background

Dendriform pulmonary ossification (DPO) is a rare disease characterized by the presence of mature bone in the lung parenchyma with typical radiologic findings of diffuse and numerous calcified nodules. We present two cases of primary DPO complicated by recurrent spontaneous pneumothorax.

Case presentation

Case 1 is a 53-year-old male with recurrent pneumothorax unresponsive to chest tube drainage or subtotal pleurectomy via video assisted thoracoscopy (VATS) who was finally treated with talc pleurodesis. Chest computed tomography (CT) revealed bilateral partially calcified reticulonodular opacities with a basal predominance. VATS biopsy revealed patchy foci of fibrous organizing pneumonia with multifocal ossifications confirming DPO histopathology. Pneumothorax re
