Chest computed tomography (CT) revealed a 1.8 cm nodular lesion with an ill-defined margin in the right lower lobe, suggesting lung cancer without metastasis (Figure 1(a)). Three-dimensional CT revealed normal bronchial anatomy (Figure 1(b)).
(a) An emergency chest computed tomography (CT) showed the middle lung lobe had been pushed upward and forward, and the right upper lung lobe had twisted dorsally. (b) The right upper bronchus with hilar peribronchovascular soft tissue edema (arrow). (c) Three-dimensional CT scan of bronchial stenosis (arrow). (d) Emergency bronchoscopy showing severe right upper bronchial stenosis (arrow). RUL: right lower lobe; RML: right middle lobe.

An emergency chest computed tomography (CT) revealed the right upper bronchial stenosis with hilar peribronchovascular soft tissue edema (PSTE) because the middle lung lobe had been pushed upward and forward, and the right upper lung lobe had twisted dorsally (Figures 2(a) and 2(b)). Three-dimensional CT scan showed severe bronchial stenosis (Figure 2(c)). Emergency bronchoscopy revealed severe right upper bronchial stenosis with an eccentric rotation and severe edema (Figure 2(d)).
Follow-up chest computed tomography (CT) on postoperative day (POD) 3 with the (a) lung window, (b) mediastinal window, and (c) three-dimensional image revealing improvement of the hilar peribronchovascular soft tissue edema and right upper bronchial stenosis (arrows). (d) 3D-CT on POD 14 showing the counterclockwise rotation of right upper lung lobe and improvement of the right upper bronchial stenosis.

A follow-up chest CT on postoperative day (POD) 3 revealed improvement of the right upper bronchial stenosis; she subsequently received 30 mg oral predonine for 7 days (Figures 3(a)-3(c)). 3D-CT on POD 14 showed the counterclockwise rotation of right upper lung lobe but obvious improvement of stenosis of the bronchus (Figure 3(d)).
