Chest CT images and eosinophils in BAL. a-c CT scans showed multiple infiltrates in the lower left lung and ground-glass opacities in the subpleural regions of both upper lung fields; d eosinophils were observed in BAL (arrow); e-h double-lung disease was largely absorbed after 2 weeks; i, j pulmonary CT scan indicated improvement and resolution of the lesions 2 months later; k, l CT scan after 5 months

Chest CT revealed infiltrates in the lower left lung and ground-glass opacities in the subpleural regions of both upper lung fields (Fig. 1a-c). BAL showed 14% eosinophils (244 x 105 mL) (Fig. 1d). During treatment, the patient had no obvious symptoms, and the chest CT was reviewed after 2 weeks (Fig. 1e-h); a peripheral eosinophil count was also determined (4.0%; 0.17 x 109/L). Chest CTs were reviewed after 2 and 5 months (Fig. 1i-l) along with a normal peripheral eosinophil count.

Chest CT images revealed multiple ground-glass opacities in the regions of both lung fields (Fig. 2a-c). BAL showed 17% eosinophils (260 x 105 mL) (Fig. 2d). The patient's chest CT images were reviewed after 1 month (Fig. 2e-h).

Chest CT images and eosinophils in biopsy specimens. a-c Chest CT revealed a number of small nodules in the upper lung and densities in the right middle lung and lower left lung; d pathological biopsy of the lower left pulmonary mucosa revealed that more eosinophils (arrow) and lymphocytes had infiltrated the local interstitium, and chronic inflammation was observed in the mucosa; e-h chest CT was re-performed after 1 month

Chest CT revealed densities in the right middle lung and lower left lung and a number of small nodules in the upper lung (Fig. 3a-c). A pathological biopsy of the lower left pulmonary mucosa showed that the local interstitium exhibited more eosinophil and lymphocyte infiltration and chronic inflammation of the mucosa (Fig. 3d). Her chest CT was reviewed after 2 months (Fig. 3e-h) and showed a normal peripheral eosinophil count (1.5%; 0.12 x 109/L).

Chest CT images, bronchoscopy and histopathological examination. a-d Chest CT showed multiple infiltrates in the upper left lung and lower right lung and ground-glass opacities in the subpleural regions of both upper lung fields; e the mucosa of the left lower lobe bronchus was found to exhibit hyperaemia and swelling by bronchoscopy; f (haematoxylin-eosin staining, x40) a pathological biopsy of the lower left lung base segment showed that a small number of eosinophils (arrow) had infiltrated the lung

Chest CT revealed multiple laminated glass shadows in the lung (Fig. 4a-d). A pathological biopsy of the lower left lung base segment showed that a small number of eosinophils had infiltrated the lung (Fig. 4f).

Chest CT revealed multiple laminated glass shadows in the left lung (Fig. 5a-c). The lung disease was largely absorbed after she used methylprednisolone 40 mg for 5 days (Fig. 5d-f), and she had a normal peripheral eosinophil count (0.1%; 0.10 x 109/L).
