Figure 1 Chest CT and X-ray findings.(A) Chest CT (January 27th) showed a nodular high-density shadow at the tracheal bifurcation, measuring approximately 8×7×14 mm. Patchy high-density shadows were observed in the left lower lobe of the lung. (B) Chest CT (January 28th) revealed occlusion of the bronchus in the medial basal segment of the right lower lobe, with stenosis in distal partial branches. Multiple patchy high-density shadows with consolidation were noted in both lungs, and localized increased lucency was observed in the left lower lobe. (C) Follow-up chest X-ray showed increased lung markings in both lungs.
