(A) Computed tomography (CT) scan at level of upper lobes showing a thick-walled cavity with irregularity of its inner contour in the right upper lobe. (B) CT scan at the subcarinal level, showing air-space nodules, tree-in-bud pattern and consolidation at the periphery of the right lung. Fissural thickening and bronchial wall thickening and irregularity. Observe also small nodules in the left lung. (C and D) CT scans obtained at the same level as (A and B) two months after showing substantial improvement of the appearance of the lesions, persisting a thin-walled cavity in the right upper lobe and scattered small nodules in the lungs.
