Chest computed tomography (CT) was performed with a prediagnosis of TB: multiple LAPs in the pretracheal, pre and subcarinal, and right hilar regions (conglomerated appearance in places); air bronchograms leading to complete air loss in the posterior segment of the upper lobe and in the middle lobe in the right lung with ectasic bronchial structures in the basal segment in the middle lobe; increased density compatible with collapse-consolidation with cavitation and increased ground-glass density in were found both upper lobes and in the posterior segment of the lower lobe in the left lung (Figure 3, 4).
