Tracheobronchopathia osteochondroplastica presenting as right middle lobe collapse. Diagnosis by bronchoscopy and computerized tomography.
Tracheobronchopathia osteochondroplastica (TO) is a rarely described disorder which historically has not been frequently recognized antemortem. Studies by computerized tomography (CT) and bronchoscopy now permit a definitive antemortem diagnosis and can obviate a more invasive diagnostic evaluation. We describe two cases of TO presenting as right middle lobe collapse, discuss the clinical and pathologic features, and outline an approach to its evaluation using CT and bronchoscopic study.
