CT scan findings of three cases. (A) Pulmonary CT results of case 1 suggested consolidation with atelectasis in the middle lobe of right lung. (B) Pulmonary CT of case 2 suggested inflammatory consolidation in the upper and middle lobes of left lung with left pleural effusion. (C) Pulmonary CT of case 3 suggested substantial pulmonary consolidation in the upper and middle lobes of right lung accompanied by significant effusion (Left: lung window image; Right: mediastinal window image).

On the 2nd day, pulmonary CT suggested substantial pulmonary consolidation in the upper and middle lobes of the right lung accompanied by significant effusion (Figure 1C).
Fiberoptic bronchoscopy results of two cases. Fiberoptic bronchoscopy revealed the formation of plastic bronchial tree in the airway of (A) case 1 and (B) case 2, indicating plastic bronchitis. Histological examination of case 2. Pathologic findings indicated that case 2 was confirmed to have plastic bronchitis.
