Résumé
Lymphobronchial tuberculosis (LBTB) is tuberculous lymphadenopathy affecting the airways, which is particularly common in children with primary TB. Airway compression by lymphadenopathy causes downstream parenchymal pathology, which may ultimately result in irreversible lung destruction, if not treated timeously. Computed tomography (CT) is considered the "gold standard" for detecting mediastinal lymph nodes in children with TB. CT is also the best way of imaging the airways of children with LBTB. The CT findings of the parenchymal complications and associations of LBTB on CT have been described, but no severity classification was provided to aid management decisions. Identifying the parenchymal complications of LBTB and recognizing their severity has clinical relevance. Using prior publications on LBTB and post obstructive lung injury we have used an image bank of CT scans in children with pulmonary TB, presenting with airway symptoms, to create a CT severity staging of lung injury in LBTB. The staging focuses on distinguishing nonsalvageable destruction (nonenhancing or cavitated lung) from salvageable lung parenchymal disease (enhancing and noncavitated) to inform the management decisions, which range from bronchoscopic airway clearance to surgical decompression of the compressing nodes.
