Endobronchial spread of tuberculosis on chest radiograph and CT

(A) Chest radiograph shows poorly defined areas of increased opacity in the lung apices and innumerable bilateral small nodules involving mainly the upper lobes.
(B) CT demonstrates bilateral apical cavities, ground-glass opacities, small areas of consolidation, and numerous centrilobular nodules.
(C) CT at the level of the lower lobes shows numerous bilateral centrilobular nodules, characterized by measuring 2 to 4 mm in diameter, typically occurring in clusters, and being centered a few millimeters away from the pleura and interlobar fissures.
