(D, G) CT scan images from reexamination after 10 days of antibacterial treatment, which show obvious bronchiectasis. Image (H) was taken on the same slice 5 days later, which showed further bronchiectasis, with internal separation. (E) Shows pathological Aspergillus hyphae and small round spores (HE ×400).
