CTICasesPost-Tuberculous Bronchostenosis
Imaging findings
Chest radiograph and CT show a small, hyperlucent left lung with marked volume loss and decreased pulmonary vascularity. High-resolution CT demonstrates severe, concentric narrowing of the left main bronchus, associated with calcified hilar and mediastinal lymph nodes.
Key takeaways
Endobronchial tuberculosis is a common manifestation of TB that leads to severe, cicatricial airway stenosis. Long-term sequelae include chronic bronchostenosis, causing persistent lobar or whole-lung atelectasis, hyperlucency from air trapping (Macleod/Swyer-James-like appearance), and secondary pulmonary vascular attenuation.
