Radiologic features in a girl diagnosed with humidifier disinfectant-associated interstitial lung diseases at 37 months of age. (A) Initial chest computed tomography (CT) after 3 weeks of development of symptoms including mild cough, decreased oral intake, and dyspnea. (B) Chest CT after 2 weeks of hospital administration. Combined air leak syndromes, patchy consolidation, and ground-glass opacities are observed. (C) After 3 weeks of hospitalization, the air leak syndrome was improved; however, diffuse centrilobular ground-glass opacities were observed with relative subpleural sparing. (D) In the resolving period, the centrilobular opacities disappeared with the remnant faint centrilobular nodules.
