CTICasesDendriform Pulmonary Ossification
Imaging findings
Chest CT shows a fine, dense, reticular pattern concentrated at the lung bases. Dual-energy CT with soft-tissue subtraction clearly highlights this branching, dendriform pattern as mature bone tissue. The esophagus is noted to be dilated and thickened.
Key takeaways
Dendriform pulmonary ossification is characterized by branching, mature bone formation within the alveolar spaces and interstitium, typically in the lung bases. It is strongly associated with chronic, low-grade recurrent tissue injury, most commonly chronic aspiration from esophageal dysfunction or gastroesophageal reflux.
