Patient's computed tomography (CT) scan images at three time points. Initial CT scan (Day 0) showed that bilateral diffuse nodules separated by the fissures and pleura. Some of the nodules have a "tree-in-bud" appearance. After treatment, CT scan (Day 9) showed visible absorption of diffuse nodules in both lungs. Follow-up CT scan (Day 31) showed that the bilateral diffuse nodules absorbed completely.

Therefore, the patient came to our hospital where chest CT showed diffuse centrilobular nodules in both lungs, some with a "tree-in-bud" appearance (Figure 1), and multiple enlarged lymph nodes in mediastinum and bilateral axilla (Figure 2). Before discharge, SpO2, blood cell analyses, and related inflammatory markers were reexamined (Table 1), in which SpO2, CRP, and ESR were normal finally, and reexamination of the chest CT showed visible absorption of diffuse centrilobular nodules in both lungs (Figure 1). Three weeks after discharge, a follow-up CT showed that the diffuse centrilobular nodules in both lungs absorbed completely (Figure 1).
Mediastinal window of patient's initial computed tomography (CT) scan showed multiple enlarged lymph nodes in mediastinum and bilateral axilla.
