Fig. 1. —Contrast-enhanced CT at level of right upper lobe (RUL)
bronchus (A and B) shows narrowing of anterior segmental
bronchus (arrow). At level of right middle lobe (RML) bronchus
(C), dense RML consolidation, narrowing of RML bronchus, and mildly
enlarged hilar nodes are seen. Bronchoscopy performed after 2 months of
treatment shows blue-black hyperpigmentation at orifice to medial and lateral
segment of RML (D). The RML lateral segmental bronchus is narrowed.
After 6 months of antituberculosis drug treatment, patency of RML bronchus has
been restored (arrow) and RML collapse/consolidation is no longer
present (E). RUL parenchymal disease has largely cleared, and anterior
segmental bronchus (arrow) is no longer narrowed (F).
