(A) Abdominal computed tomography (CT) revealed mixed reticular and ground-glass opacities in both lower-lung zones. (B) Chest radiograph on admission showed no specific abnormality. (C, D) High-resolution CT showed intralobular reticular and ground-glass opacities in both lower lobes, the right-middle lobe, and the left lingular segment. Band-like thickened intralobular septa were also observed.

Instead, the abdominal CT revealed ground-glass opacities and intralobular reticular pattern densities on both lower-lung fields (Fig. 1A), although there was no abnormal finding on her chest radiographs (Fig. 1B) and she did not complain of respiratory symptoms, such as dyspnea, cough, sputum production, or chest tightness. An additional high-resolution CT (HRCT) scan showed the same findings, suggesting interstitial lung disease (ILD) (Fig. 1C and 1D).
