case_images: Chest computed tomography (CT) showed multiple pulmonary nodules, but no abnormal findings suggesting accumulative lung damage such as fibrosis ( Figure 1 ). The pathology showed that there was only fibrosis around the tumor as a tumor environment, and there was no obvious fibrosis in the background lungs consistent with the CT findings ( Supplementary Figure 1 ).

case_images: A CT scan showed no apparent tumor growth, but there were slight bilateral ground-glass shadows ( Figure 2 ). The clinical course after onset of DILD is summarized in the  Supplementary Figure 2 .
