Figure 6 (A-F): CT features highly suggestive of active TB. (A) CT chest (lung window) showing centrilobular nodules in tree-in-bud pattern involving right upper lobe and superior segment of right lower lobes. (B) CT (lung window) showing consolidation in bilateral upper lobes and superior segment of right lower lobe (black arrow). (C) CT chest (lung window) showing randomly distributed miliary nodules in bilateral lung fields. (D) CT chest (lung window) showing thickwalled cavity with surrounding consolidation in right upper lobe. Extensive centrilobular nodules are noted in adjacent lung parenchyma. (E) Coronal reformatted image of CECT chest showing conglomerate lymph nodes in right upper and lower paratracheal and subcarinal region with obscuration of perinodal fat (white arrow). (F) CECT chest showing right-sided empyema with split pleura sign. Note made of volume loss in right hemithorax with crowding of ribs
