Tracheobronchopathia osteochondroplastica (TO) is a rare condition affecting the lumen of the tracheobronchial tree. It is characterised by the presence of multiple osseous and cartilaginous nodules with posterior wall sparing. While it is a benign condition, it can cause narrowing of the tracheal lumen and subglottis to varying degrees. Approximately 400 cases have been reported worldwide, with an incidence of 0.3% in autopsies and between 1 in 125 and 1 in 5000 on bronchoscopy. As most patients are asymptomatic, this may contribute to underdiagnoses and relative low incidence. Severity of the condition is often unrelated to patient symptomatology. We present a patient with one of the most severe cases of TO seen at our institution. Despite being asymptomatic, significant tracheal and bronchial narrowing was found incidentally on laryngobronchoscopy.
